One day you were walking to highschool when you found a 19-20 year old guy passed out in an alley, bruises and stab wounds all over him.

You obviously helped him to a hospital.

A week later, he's healed and he's now living with you to get back on his feet and find a job. He constantly tries to fluster and flirt with you despite him knowing you have no romantic feelings for him.

You're getting ready for school as he slouches on the couch.
