Heesu in Class 2 — Pretty Hearts, Weird Focus, and a BL That Forgot Itself
A Korean Boys’ Love adaptation of a beloved webtoon sounds perfect on paper. But what aired in 2025 felt like a BL story stuck in neutral — unsure whether it wanted to be a high school romance, a slice-of-life love story, or a straight teen drama with an accidental queer subplot.
This should have been about Heesu falling in love with Seung-won — a painfully slow, awkward, tender, unrequited kind of love that builds so beautifully in the webtoon. But instead, the straight side plots — especially Heesu’s best friend Chan-yeong and his girlfriend — take up so much time that the real romance doesn’t start until nearly the last quarter of the series. That’s exactly what many viewers online complained about: the adaptation shifts focus so much that the BL only becomes real when the drama ends.
It’s like watching a show called Heesu in Class 2 and realizing half the episodes might as well be titled Chan-yeong and the Tennis Arc.
Honestly, the acting and chemistry were really good. Ahn Ji-ho as Heesu brings that shy, stargazing kid energy — awkward, sweet, and lovable — and Lee Sang Jun as Seung-won, the quiet admirer next door, plays his frustration and longing very well. Their scenes together are once-in-a-while gems that make you go “Why didn’t we get more of this?” — because when the spotlight is on them, it almost feels like what the series should have been. Even fans online acknowledge the actors’ natural energy, and many say their scenes were the best parts of the show (and not by accident — people were shipping them hard).
But the story is just so unfocused. There are subplots about sisters’ romantic lives, drama around tennis, and a whole straight romance that moves extremely fast compared to the main queer storyline. That might be fine for a general K-drama, but for a BL adaptation? People expected the Queer Love to be the priority — not the side quests.
One of the biggest complaints online (and honestly, I agree) is how the confession build-up gets dragged out forever. Heesu is oblivious, misunderstanding, and stuck in silent pining for so long while Chan-yeong’s relationship moves at real speed. Viewers on Reddit straight-up called Chan-yeong’s behavior “selfish,” and said it felt unrealistic for a best friend — like the narrative was making the queer character wait forever only to make the whole emotional arc feel anticlimactic.
In the webtoon, the focus is tight. Heesu’s inner life, his longing, his growth — that’s the meat of the story. In the drama, those beats are diluted among irrelevant arcs that slow the pace and blur emotional impact. That’s exactly why so many fans felt let down: they signed up for a Heesu-Seung-won romance and got something that felt like two shows in one instead.
Even the music and the pacing emphasize that relaxed, almost filler vibe. The songs are pleasant enough but never resonate with what should be the emotional core. And by the time the BL arc finally shines, the series is already over — and you’re left feeling like you watched everything wrong. That awkward feeling of waiting for love to show up… and it finally does… after the show is basically ending — it just made me go “…is that it?”
I’m not here to say there’s no good in this drama. The cast is likable, the production is clean, and there are moments where you almost feel the chemistry you were promised. But overall? It feels like a story that was too scared of its own identity. It tried to balance multiple romances, too many subplots, and ended up diluting the thing that should have been the heart of the show: a queer love story told with honesty and focus.
And that’s why the overall feels so low.
If you’re looking for a real BL romance that feels like BL, this might frustrate you. But if you’re okay with a light teen love drama that only briefly flirts with queerness, you can still find moments — like little sparks in the night sky — that remind you of what the show almost could have been.
