I always confuse Their names

Jaewon - main mc with dusty blonde hair, likes Karam but is currently thinking about Junseo
Karam - brown hair with blue eyes, he dumped Jaewon but he actually likes him too
Junseo - black hair with yellow eyes, Jaewon’s friend but he actually likes Jaewon
Yoonsung - red hair, used to be liked by Jaewon when they were kids, idk about his feelings for Jaewon though (he looks like at some point he did like Jaewon but he hasn’t admitted anything)
Jaehee - orange hair, Jaewon’s friend, he looks straight(?) he had a beef with Junseo before but they’re good now
Hana - long haired girl, Karam’s childhood friend and is a good friend of Jaewon

Okay...let me help you with this...
Karam is the main focus on this new chapter. one with black hair. He apparently discovered(?) that he likes jaewon.
Jaewon is the mc with grey hair. He liked Karam and used to like Yoon Sung.
Junseo is one with black hair. Taller than Karam and Jaewon. He's been friend with Jaewon due to their mutual condition of liking man. He likes Jaewon too.
And then we have Yoon Sung the one with red hair. I don't know what's his deal tho. Doesn't look like he really likes Jaewon.

And that's all the main characters for this story. Hope it help though quite late.

Thank you so much! ^^
