Very similar characters and themes of fate and sacrifice, and finding your loved one through multiple lives /over time. I personally liked the visuals better in Song of the Moon. I suspect this would have been more popular and well known if it hadn't been overshadowed by Love between a Fairy and a Devil, which came out around the same time. FYI this has two possible endings and you can decide which you prefer (which may also be why it doesn't get the attention it deserves). An underrated drama, and a good watch.

Both focus on weak and timid teenage boys who experience bullying at school, which pushes them to learn how to fight back. As they grow in their fighting skills, they also mature and develop in personality, making new friends and enemies along the way. Both become underdogs and work hard to get stronger and better.

RB focuses more on MMA and structured competition, while Boyhood features street boxing, but both include a lot of satisfying ass whooping.

Two friends, Kyung Min and Detective Jong Suk, reconnect after receiving a message from a friend they haven't heard from in 20 years. The message triggers painful memories of their school bullying, and soon after, a series of mysterious murders begin. As Jong Suk investigates, he uncovers connections to the past, while the drama explores the origins of school violence and its enduring impact on society.

This is very similar… everything is very similar if you liked Serendipity you will definitely enjoy Are You the One more

“Go to the Mountains and Sea” is a journey of seeking freedom, wonder, and an escape into something bigger than yourself — much like A Dream Within a Dream, where reality feels blurred, fragile, and dream-like.
Both works carry the feeling that life is fleeting, that what we touch may vanish like sand slipping through our fingers.
When you ‘go to the mountains and sea,’ you are chasing a dream within a dream — a longing for something pure, eternal, and real, even if it feels impossible to hold onto.
If you loved the bittersweet, questioning feeling in A Dream Within a Dream, you will find the same spirit of mystery and yearning in Go to the Mountains and Sea."

They both have same genre and I am waiting for both the dramas they both are my favourites I am waiting for both these amazing dramas!!!!!! Fighting!!!!!!

this season reminds me so much of study group, in both series they have to fight with an organization led by a person of authority of the school, i think gaku and baek jin have the same style of fighting and in study group ga min and ha ul have also the same style and the same ability , in their friend group they also have some people who fight and some people who doesnt

Both shows have a similar vibe: historical setting, two male leads trying to clear their master's name, and a romantic relationship between the ML and FL where she initially believes that they are siblings . The mix of mystery, loyalty, and slow-burn romance is strong in both, making them feel deeply connected in tone and story.
