When I read this chapter, I thought that him returning because without Dojin, he'll die was just a poor excuse that conveniently came up because of the bond because he's still somewhat unsure and in denial of both his feelings and Dojin's feelings. The fact that he couldn't get Byul's face out of his mind and questioning why Dojin loves him indicates that they are the real reason for returning. But who knows XD Maybe it's just my optimistic side saying this.

Damn I wanted uke to come back because he loves seme and the baby not just cause he’s gonna die without him but it’s still cute tho
