Obsessed /Possessive /Twisted Ml (BL)

Rookie programmer MC x Npc ML
Imagine transmigrated into the game you developed yourself and be able to interact with your self made characters how sweet, right? But what if that character is actually a killer who is ready to kill you any moment (but he is cute tho~)

MC calls himself ML's father because technically he created him

And don't worry ML is a sweetheart just don't understand human emotions (i mean even we humans can't understand it let alone a Npc)
