Okay so as you may or may not know ml's brother r*ped Mc and when ml finds out he gets so angry so he r*ped Mc too (!??) Anyways them Mc gets pregnant and he's already depressed and not sure who the baby's father even is, so he decided to shoot himself. That time before he pulled the trigger, he unexpectedly encountered ml at the door stupefied at the scene in front of him. Mc was holding the gun towards his heart, pulled the trigger infront of ml, and later on died. As ml held him, he was crying as he tried to stop the bleeding of mc's chest.
Later on, during a conversation between ml and mc in the second timeline, mc discovered that ml died later after him. In which ml while crying only replied, "I'm sorry". (It wasn't mentioned how or when ml died in first timeline, but i think probably suicide too.) It was also revealed in this conversation when mc asked who is the child's father, ml confirmed it was his.
I'm Everywhere.
