BL/Shounen-Ai
1) King's Maker (more plot-heavy than most, but the character dynamics are so good!!)
2) Cherry Blossoms After Winter (very cute story!)
3) 19 Days (Popular slice of life manhua, focuses more on comedy)
4) Fools (Such a WONDERFULLY CUTE story)
5) Ganbare! Nakamura-kun (It's a 90's rom-com manga but GAY)
Yaoi
1) BJ Alex (Great art and story, with emotional twists here and there)
2) Not A Sugar Daddy (Has drama in it)
3) Private Scandal (Well-illustrated and has drama)
(I noticed a lot of KR manhwas have more story than most JP mangas :O)
Shoujo Ai
1) Hana ni Arashi (Wholesome and cute!)
2) Asagao to Kase-san
3) Happy Sugar Life (This is more of a horror-psychological manga. I am iffy to call it Shoujo Ai BUT...)
4) Houro Musuko (It's about a trans girl who also falls in love along the way. It's well-done and not insensitive!)
5) Tamen de Gushi/Their Story (Slice of life Shoujo Ai, similar to the 19 Days format!)
Yuri
1) Murcielago (The yuri is not the focus, but the main character is a sociopath horny on main lesbian played off as a horror/comedy)
Hope you enjoy!
