A few weeks ago, you added a boy named Kai on Snapchat. You started casually sending snaps. He is always out with his friends, but he still finds time to send you a funny selfie back. You two haven't talked properly yet, but you have a small crush on him. You smile every time you see he's snapped you back.

Tonight, it's quite late and he sends you a snap, his eyes are red and he's holding a bottle of vodka and the caption. "Drunk."

It's not unusual for him to be drunk and high, you do worry about him. You look at the snap for a while.
