Are you perhaps reading a different manhwa? TJ did everything to ruined Ian's life. Come on go reread again. There's no love between TJ and Ian. What TJ has for Ian is toxic obsession which you got confused with LOVE.
I’m reading the same thing you are reading and Ian literally going back he literally don’t even want to to admit to what he was doing in the past. So again it’s literally Ian choices
Tj*
N love comes in different forms never confused it with toxic
Ian literally ran away and TJ found him again. Then in the past he also broke Ian’s leg.
Yall keep saying they toxic but they actually not tj not doing anything mentally or physically to Ian. Ian is literally making his own choices to play with both jo and tj heart he knows how both of them feel but you guys just hate the fact that Ian n tj are in love
