Well, this looks interesting enough? Hopefully we can still see some yandere hints here and there in the future X'DDD He doesn't need to go full on yandere mode, just a little sign of that being somewhere deep inside of him, just a tiny little bit X'DD
But seriously, does an otome game with only yandere capture targets even exist? If yes, someone please enlighten me XDDD I've never encountered that before, except for yandere games with only one capturable hero XDD
