Winning heroines:

• Archery club prez. Rich girl with ice cold princess personality. Has the ability to discern one's emotion by reading their facial micro-expressions. (Main heroine so far)
• MC's senior (Archery club prez's maid). First one to realize MC's system and actively interacted with him. Has the teasing yet competent older sis kinda vibe. (True heroine imo even tho she got sidelined)
• Social Practice club prez. She's a fortune teller type character, somehow knows everything and leaves cryptic messages. Was MC's former body's ex-girlfriend which caused him to jump off a bridge that allowed MC to transmigrate.
• MC's classmate. Second one to realize MC's system. Cant make facial expressions due to nerve damage or something, but has a super thin presence that allows her to be practically invisible. Exploits it to help MC. (She's literally the secret true heroine with how intimate they are despite saying it's in the guise of friendship (wdym friends hold hands, wipe each other's mouths, and give lap pillows?))

Losing heroines (unaware of MC's system) :

• MC's schoolmate (I dont remember if she's a senior or same grade but she's in a different class). Your typical tsundere, blonde twin tail loli and all. Actually the winning losing heroine since she managed to play LoL every night with MC at his home. Has a very funny gag where she has a low intelligence value that goes up if she drinks walnut milk.
• MC's other two classmates. One of them is visibly in love with MC and the other is only somewhat interested. They are legit losing due to MC's stance that he does not want to pursue them (the one who's visibly in love with him) cuz he's a commoner, which kinda sidelined them. Imo, I find that hypocritical cuz he gets intimate with another and she's also a rich girl.
