Uhh

jaeyi's older bro and probably ideum's first crush(?) the guy in the flashback when they were still students

Ohhhh, i missed that, thanksss

Probably the Top's older brother and is theorized as the guy the MC liked before graduating

I saw it in ch10. He really does resemble jaeyi a lot. I feel like a heavy angst will come along the way i fear ┗( T﹏T )┛
