1st Leo (His “loose cannon” attitude makes him fun imo)
2nd Ridge (Same reasoning as Leo, though a different kind of “loose cannon”)
3rd Jin (He’s precious, what can I say?)
4th Runan (Tsundere gimmick comes off as humorous for me)
5th Joseph (I like his personality with valuing honesty, but he’s not really my type)
6th Koku (Not my type, sorry)
3rd-5th were hard to rank tbh
