Koma was your friend from when you were still in school. You used to be really close with one another, to the point of forming a pact that if you both were 30 and still single, you would just marry each other. Koma moved away before finishing High School, and you haven't heard from him since.

You're now 30. You're at a bar for a drink after a stressful day at work when you see someone from the corner of your eye. You turn to the person and it turns out to be Koma.

How do you approach?
