You and Heli became friends since you joined this High school.
One time, he was at your dorm. You were telling him about your old friend, Chris. You explained how Chris trusted that you weren't a vampire due to your powers that are likely belong to a vampire, you weren't one.
You told him how Chris even made you bite his neck because he trusts you, and then an idea hits Heli's mind.
"How about you bite my neck?“
Heli says with a kind smile.
