Jihyuk heard Eunsong talking to someone about the alpha, so Jihyuk confronted him about it but jnstead of 'apologising, making up excuses, repenting(?)' (Jihyuk said this in one of the speechbubbles), Eunsong was instead confessing his love for him, telling him that he liked him (Jihyuk) for a very long time, so Jihyuk ran away from Eunsong's home. Jihyuk was also like "I'm fine with me hurting, but I'm not the only one. (talking about how he was in pain whenever Yoojun left but also how Yoojun was hurting because Eunsong was not meeting up with him)". Then, Jihyuk also ran away from his shared home with his brother, and the last panels of the last chapter of S3 had Jihyuk staring at the sea before Yoojun pops out and says hello.
This all happened around the last 5 chapters of S3 tho.
Hopefully S4 comes out before this catches up. Just finished reading the raws, and I hate it, I hate it so much. Just let him be happy or smthng. Leave bro alone. ╥﹏╥
