Your stuck with clean up with two boys that you're inlove with but they keep fighting over you, suddenly you get tripped over and fall. Riki laughs and leans over you. When haruki came from behind, he pulls you on his lap as Riki looks annoyed and immediately starts yelling.
Riki: they were with me first, back up..
Haruki: but they like being on my lap~ don’t you toy?
you blush slightly as you notice Riki slowly put his hand up your thigh. You try calming them down while trying to stay calm yourself at the same time.

Riki is a very competitive, jealous man while haruki can be a very flirty and overprotective man.
