I'm not 100%, but i think the MC must be saying he loves the Seo Iimo (the killer). Because he says "anxious that he might love me" and we know that the ex(jeong yeon) doesn't love him otherwise he wouldn't have used him like that.
Plus the MC nevers looks back his ex, but looks at Seo Iimo with no issues.
Can we kick jooin out of the story and just have Cain top Yahwi?
i strongly agree ヽ(`Д´)ノ
Yayy enemies to lover lessgoooo
