Idk if yall remember but somewhere in the previous chapters, Angel was already mentioned about how he likes his presents getting personally handpicked for him. And that he's his mom. In the spoilers ive seen in novel updates, he kissed his son bc of the presents he received. (Ik its weird but its for the sake of the plot and misunderstandings xD)

Oh and spoilers~ (about what happened to Keith after Yeonwoo got missing)
When Yeonwoo got missing, Keith stopped messing around... And became an alcoholic. The company almost got bankrupt, in other words, he became a mess after Yeonwoo left. Oh and guess what, when Keith's rut arrives, he goes to an island all alone and suffers there. Turns out, this hoe actually likes Yeonwoo but he doesn't know how to express love... except through money xD
Yall the person he's kissin on the last panel is Angel xD
Angel is his mom I think.
