A shame, I agree. But what can we do? Despite that, I think he seems more human this way, you can see his childishness coming out when it involves Yeojoon.
In addition to that, athletes in real life end up focusing majority of their years/time and attention to their sport, and less on normal relationships outside to learn from, for overall values and behavior we deem acceptable.
I'm afraid Jihoon's reactions throughout the manhwa seems a bit plausible (at least to me XD) i'm just glad that despite his obsessions, he is somehow not a blatantly toxic asshole. He shows qualities that he is capable of good change for his BF.
Slightly hoping theres some form of addressing the things he did and giving him time to make up for it sincerely We would love a green flag that learns from their past mistakes and strive to better themselves for their baddies
(Yeojoon himself has his own flaws but who are we to chide them, smh. Theyre both my shaylas idc)
Sigh another green flag down the drain..
