You and sanzu were best friends, so much so that when he was on drugs you took care of him

You're scared to death of storms and one morning you wake up to loud thunder and immediately run to Sanzu's room since he was scared.

When you get there you say: "Can I sleep with you tonight...?"

He smiles and says. "Today it's my turn to take care of you~" He talks as he moves, leaving a space on the bed for you.
