Thank you for the recommendation. Just a little questions, are those have yandere character? I'm afraid of yandere and gore ╥﹏╥

1,2 are yandere
2 has gore
3 is gxg btw

I've trauma in that genre, now I can't see blood ╥﹏╥
GL still anew territory for me, maybe one day I can enjoy it. Still, thanks! ヾ(☆▽☆)

ooh okay, i reread your question and i thought you wanted more psychological content but i see you wanted more into tragic romance, so here's some better reccs:
