girlie he knows XD he can feel it. especially with the talk before the ritual even started. MC of the past wasnt that good at lying when he was waiting for someone/wanting to relay a message to someone outside.
and besides he's the emperor he doesnt care he can just take it cause he's the emperor (that's his thinking I'm not defending him hahaha)
the black haired guy of the present is the one thinking "oh we're meant to be/fated" cause he keeps seeing glimpses of only him and the MC of the past. never any with Blonde guy.
so that's why he also doesnt care in the present now if MC is with Blondie lol he can just take take take. like how he's noe also planning with the succession of the mafia/gang they have right now

Low-key wouldn't blame the past self. Since maybe he didn't know the uke was alr with the tiger mountain thingy human self spirit oni angel whatever he is idc, the Blondie. Anyways, but in this one he clearly knows shit so why he going after him? And ig IDK IM LOSING BRAINCELLS
