18-year-old Hui Su is an ordinary high school student who considers himself a "dating expert," though he has never been in a relationship and has been single since birth. Secretly, he harbors feelings for his best friend of ten years, Chan Yeong, but keeps this heavy secret to himself, nurturing his feelings alone. Meanwhile, Chan Yeong discovers that his favorite singer, Summer, is actually Ji Yu, a fellow student at their school, and he starts showing interest and developing affection for her. Feeling a sense of crisis at this unfamiliar side of Chan Yeong, Hui Su teams up with class president Seung Won, who has a crush on Ji Yu, to win back Chan Yeong. However, for some reason, Seung Won seems more interested in Hui Su than in Ji Yu.

The correct title: Heesu In the Background Of Class 2.
I loved Hee Su and Seung Won, but if we actually gathered all their scenes it would be the length of a fan made youtube video. They were both sidelined getting supporting characters treatment in their own story.And no, I do not only mean romance wise. Which characters got more elaborated individual stories presenting them outside of their love lines? Chan Yeong with his Tennis arc and Ji Yu with her music. What about Hee Su and Seung Won? Nothing. I’m sorry, but if you describe the plot of the drama to a person, Hee Su perfectly matches the typical second male lead - in love with the male lead, trying to win him over, to give up when the female lead shows up. Ending up with the female lead’s best friend.
No amount of pretty poetic narration done by Hee Su will convince me he got the proper treatment as the main lead of the story. For me, these lines sounded great, like out of context motivational quotes, since the episodes often did not focus on his perspective enough to validate their existence. I mean… even in the last episode could not have been all about the mains, we also needed a montage of the love story of the second leads.
If I was to rate just Hee Su and Seung Won, it would be a good 8. They were sweet and fun to watch. The misunderstandings actually seemed realistic for their age. The low key pinning was great. Seung Won was just calm perfection - so many of his simple few words amazed me - the simplicity with the greater message behind them was just right.
But then we have Chan Yeong and Ji Yu. I would not even be that mad if they were not just so painfully boring both as a couple and as individual characters. But to take away from the gay couple, to focus on this mediocrity is just a crime.
Maybe because their characters did not have much to offer, the acting also felt mid. Ahn Ji Ho though - amazing. The hesitation around his crush, the glasses he kept stealing, the anger and the frustration when certain things came out to light.
The production value was obviously a lot better than many other k-bls - the bigger budget was clear. Can better production quality save uneven writing? Probably not.
Overall, disappointment. I was one of the people who was not initially angry about the straight couple, but I was still naive thinking they will stay in the sidelines complimenting Hee Su’s and Seung Won’s story. I did not expect them to come to the forefront and stay there till the end.

A promising yet unfulfilled journey
Prior to touching on any unfavorable points in the adaptation, I would be remiss not to praise the decision made by Ahn Ji Ho and Lee Sang Jun to take on roles that break the conventional heteronormative mold. Special recognition goes to Ji Ho, who, having starred in a popular mainstream Zombie drama "All of Us Are Dead," shows immense courage in embracing a non-straight role and sets an example for other mainstream actors. The interaction between these men is endearing. Sang Jun (Seung Won in the drama) is a timid/shy, lovesick admirer, striving to capture Ji Ho (Hee Su in the drama)'s attention. Much like the source material, drama Seung Won's motive for approaching, reaching out to, and confiding in drama Hee Su is to spend more time in his company and reveal his feelings for himSeung Won: "I don't like Ji Yu"
Hee Su: "Why did you lie?"
Seung Won: "Because I wanted to keep hanging out with you" (chapters 42-43)

Drama Seung Won, too, gently nudges drama Hee Su to confront his true feelings and discover the solace and true love that await him in Sang Jun (Seung Won)'s arms
Apart from Ji Ho (Hee Su) and Sang Jun (Seung Won)'s chemistry, a praiseworthy part is drama Hee Su's compassion. In the first episode (5:10-7:04), he listens without prejudice to a woman struggling with her feelings for another woman. There's something extraordinary about the scene. It's become one of my favorites!
Now, this might be a contentious point. I find that the actors’ and actresses' appearances don’t match the youthful roles they’re playing. Without a doubt, they're good-looking, but they give off the impression of being older and in their mid/late twenties or early thirties. Their seasoned, mature appearances prove challenging to reconcile with their student status. And watching them cosplay as high school students sometimes stretches my ability to suspend disbelief to its limits. An effective approach could've been to set the story in a workplace or university
I can be lenient with these matters, most high school dramas/movies have the same problems. What troubles me is the pacing and the straightwashing or forced feeding of "straightness" to cater to the squeamishness of homophobic mainstream audiences wary of encountering too many rainbows on their screens. The pacing of the gay storyline is sluggish compared to its "straight" counterpart, suggesting an uneven distribution of resources and dedication from the producers. It's not until the seventh or eighth episode that the emotional bond between the gay couple undergoes transformation. The adaptation struggles with maintaining the integrity of the source material, a problem worsened by the presence of a "straight" storyline
The source material doesn’t even feature a "straight" storyline between Chan Yeong and Ji Yu. I find the insistence on shoehorning one into the narrative, and replacing Sun Woo and Yoo Dahm’s (the second gay couple's) storyline, unforgivable. A screenshot of Sun Woo and Yoo Dahm from chapter 56: https://imgur.com/a/OInfwbQ
How mind-boggling it is that we're accused of "destroying" friendships for shipping characters of the same sex who are "just friends" in their source materials when society destroys or hints at destroying man-woman friendships in favor of non-platonic storylines with nary a consequence. Friendships between men and women, boys and girls, are meaningful and don't require a non-platonic downgrade. Chan Yeong and Ji Yu serve Hee Su best as supportive friends. Inserting a "straight" angle between them detracts from Hee Su's journey. This story, "Heesu in Class 2," belongs to Hee Su and his love interest, Seung Won, and shouldn't be hijacked or distorted by a superfluous "straight" storyline
Some might defend the erasure of the second gay couple from the adaptation, citing that their storyline occurs in the second season of the source material. It's a dubious, flimsy excuse at best. The screenwriters were capable of fabricating a "straight" storyline involving Chan Yeong and Ji Yu. It would've been prudent to use the creativity and merge key elements of the two seasons into the 10-episode adaptation. The creative process of converting the Manhwa into a drama enables the combination of two seasons' worth of content into a condensed format. The screenwriters could've reorganized and improved on the timelines, events, dialogue, and character development of the source material. The erasure of the second gay couple is an oversight, considering the wealth of solutions available to incorporate their storyline
Being classmates and friends, Hee Su's acquainted with the second gay couple. Their early introduction in the adaptation could've provided Hee Su with close tangible evidence that happiness in a gay relationship is possible, instilling him with the confidence to pursue his own male love interest(s). Their presence could've contributed to Hee Su's personal growth. They didn't have to be "useless" or "irrelevant"
Those reading might ask themselves, "are you a hater? Do you hold a grudge against the adaptation?" I'm not, and I don't, or I wouldn't have assigned it an 8/10 rating. I believe the adaptation should've gone beyond the bare minimum of keeping one of the gay couples. And I believe everyone has a right to be uneasy about certain deviations from source materials. The sentiment was witnessed in the public's response to "The Little Mermaid" (2023) and "Snow White" (2025), where a simple change in skin color caused widespread disapproval. It's reasonable to also disapprove of changes to gay source materials
Expressing a preference for gay narratives over "straight" ones or questioning the producers' call to accommodate societal prejudices against gay-centered narratives doesn't amount to prejudice or -phobia. Releasing a work into the public domain opens it up to positive and negative feedback. Both are opportunities for the producers to understand their audience better, identify their shortcomings, and grow
That said, I appreciate the effort put into this part-BL/part-gay adaptation. Going forward, I'd like to see BLs exclusively centering gay experiences and relationships
