this is so goooooood can u give me more friends to lovers?

Spinach Bouquet
1995 Youth Report (roommates turn friends turn lovers and it is adorable)
My Guildmate Next Door
Half of Me (on hiatus and slowburn, I mean slow, slow)
Heesu in Class 2 (completed)
Turning (slowburn and rebirth)

High Clear (completed)
Red String Quests (hiatus)

I don't know if Our Sunny Days counts because the MC and ML became quick friends after he returned to Korea with his baby, but I highly recommend it if you just like pure sweet pureness!

THANKS I LOVE YOU

Check out Unsleep, too.
It's not really friends to lovers but it is a fun read. ლ(´ڡ`ლ)
