TOTALLY FIT what you want Gosh, it was so FKING GOOD Both male or female reader Also strange background world, very original Romance being quite serious Its basically similar vibes like the manga with crystal characters ~~mysteriousness~~ originality
And just like Otomoyome/Emma/serious romance There is drama (but not dogblood) confrontation about feelings growing up parenting slice of life conflicts, mega close to dangerous but of course will be solved SIDE ROMANCE(s), MEGA CHARMING
MOST importantly the ~shoujo-ish but mature and mainstream monochrome drawing style~ similar to Otoyomegatari artist
There are some short WNs of 150+ ch where the MC get a normal romance or rebirth in time, get together with the schoolgirl but "serious atmosphere"....... funnily isnt there. DESPITE CHINESE WN industry being always serious writing style (pre2020)
Ah BUT ! Maybe it FIT ! My old favorite genre of "dad" gosh, you made remember it That also explain why i like them so much, when comparing to Otoyomegatari
Before, 2018ish~ dad chinese WNs, was my "guilty pleasure/péché mignon" like PALADIN DAD or Restaurant in another world all authors wrote the romance in them in a VERY VERY serious vibe but bc of gen-z readers began to rot into stuff like "dad system" "my wife is a star giving me triplets" "after breakup, star came with child to me"
