i would like to know too
Charlotte has five disciples ( from what I remember fits the bill, haven’t read in a while though)
Tonari no kaibutsu-kun (Aka: My little monster; better fit for emotionless female lead but you’ve probably already heard of it, there’s an anime. Also exactly two guys)
Kusuriya no Hitorigoto ( kinda has emotions but not for romance. Also plot heavy; not about a ton of dudes so if you’re just looking for a reverse harem it’s not it)
That’s all I got from the top of my head
ALSO RECOMMEND ME STORIES WHERE THE FEMALE LEAD IS DEVOID OF EMOTIONS AND A LOT OF GUYS LIKE HER AND SUCH.
