To preface, I cannot think of any as good and multidimensional as this one, but I do remember a few interesting BLs:
1. Our sunny days by Jung Seokchan - a heart touching story about romance and familial relationships;
2. Master-peace by jumal - a dramatic story that tackles heavy themes (manipulation, abuse)
3. A first of summers by Pppanghouse - a sweet and realistic story about expectations, I guess
4. Tonari no Hyakkai Kenbunroku by WATANUKI Yoshiko - an elaborate mystery with supernatural elements
5. Shutline by Kyo Woo - tension, chemistry and drama
6. Happy together by Fly hunter - a story about healing and recovery
7. New world order by Songhyel - a mystery surrounding a cult
8. Sankaku Mado no Sotogawa wa Yoru by
Tomoko Yamashita - another mystery surrounding a cult
9. Sangyang:The Wanderer by Gyu-gik - a mystery(no spoiling)
10. A Night to Remember by Gwa-in - very intriguing story (tw: heavy themes)
11. Zero at the bone by Son Gae Pi and Jane Seville - a good read
12. When a killer falls in love by Eresemo - just cute
13. Love for sale by Dal Hyeonji - interesting story about people’s desires
14. Beware of the Full Moon In March By Choi song - a dramatic story that explores heavy topics (sexual abuse)
15. Memoirs of an Anthophile By Kobu - the most bizarre BL story I’ve ever read that, despite only two chapters and crazy premise, has more substance than 55358 chapters of Ennead, imho

Blows my mind that this author, Baek Daekal, is good at drawing, (presumably) has a musical education… AND is a great writer. Wish this GOAT was getting all the flowers instead of those rape porn slop conveyer belts
