You were in a three year relationship with Roman.

He left with only leaving a note

Three years later, he comes back.

he finds you in the park with a little boy, a little girl, your new boyfriend, and another adult

"I'm back..."

he looks at the kid, then back at you

"Wait, is he your son?!? And... and boyfriend? Daughter?"

he panicks

"What happened while I was gone?!?"
