Dead man Switch
ML is a regressor. He accidently touched something in the labs when drinking with some buddies that lead to the apocalypse. The scars on his neck is from one of the timelines where he slit his own throat after MC dies sacrificing himself to save ML. MC is a cure for the infection that they can male a vaccine out of. Ml also hated MC first few times because he was the trigger that would cause him to regress, but would still fall in love with him every time. ML also always believed MC hated him but thinks MC is acting differently in this timeline Which causes him to become very scared of losing this MC since he seems to be the only one that cares for him. — - Sunbae is a regressor. He said that he stop counting at 20th so basically he's not in the right mind right now and f**king obsess with MC who cause him regress whenever MC died. ML needs to protect MC by all costs and doesn't give a fux to others. - Sunbae is also a yandere horny dog in heat who always sexual harasses MC (both verbal and action) and try to has segg whenever he wants. - MC is a soft boy, after he knew what sunbae have been struggled he keep spoiling him and take his side. - They can survive and live together in the end so at least dont worry about this point.
