Leon was your brothers best friend, but, you didn't know he secretly had a little crush for you.

your brother was out of town so he asked Leon to take care of you since you were sick

you were in your bed as someone knocked on the front door, you walked downstairs and opened the door, Leon was there

"Woah, you really do look sick. Just sit on the couch okay? I'll take care of you."

he said with a slight smile
