What’s wrong with you people in the comment section?
Yukine has the mental strength of a preteen who just remembered that he was abused and murderEd by his father while the rest of his family did nothing help. Not to mention Yato’s father corruption. When Yukine needed him the most, Yato ran off without an explanation and formed a contract with someone else even though Yato constantly said that he only needed Yukine.
This is as much Yato’s fault as it is Yukine’s (though most of it is Father’s fault). Yato knows Yukine was hurting because he stung him but instead of checking on Yukine, Yato decided to avoid the problem, leading to this situation.
So why are all of you telling him to kill Yukine like it’s entirely his fault?
