Hello Rury ! sorry if I'm mistaken but I remember you asking for vn reccs a while back, so I think 僕の最愛の (Boku no Saiai no) could be right up your alley :] it's free, playable on browser, short and jp only for now and features a bunch of dark tropes with a cute art style (and cute boys). If you end up trying it I hope you'll enjoy it ^^ in any case, have a good day and please keep up the good work~
