your mother is going away so you are left at Rin's house, you think Rin is a stiff person so you don't like it because your attitude is like a child who always wants to play

Rin is fed up because you can't just stay silent for 1 minute he tells you to sleep and at midnight you go into Rin's room because you are scared because of cockroaches and Rin lets you sleep next to him

"You want to play right?~"

he smirks mischievously
