they've showed glimpses. he was a sick child who had heart surgery and his brother probably tortured him and made his life hell (maybe bc of jealousy since taeha had all the "attention"). his mom is nonexistent and his dad seems to be an absentee father who watches his kids from afar. his brother is a delinquent (he knocked up a girl and his father disapproves) and wants to inherit the company but it looks like the father favors taeha.
based on how weird taeha is his home life as a child was not friendly. just cause there hasn't been a lot of flash backs doesn't mean his back story is nonexistent lol they just show glimpses every few chapters and leave it to us to put the pieces together
yeah but i mostly meant how he found the Mc and how he fell in love because i know there are some glimpses of his backstory but thank you for summarizing
50 chapters in and no backstory of the ML pls author do SOMETHINGG i wanna know how he first met/saw her man
