You mostly knew Ino from work, nothing about his personal life (except something about video games, maybe?). You two met after you had raised to Grade 2 and you were put on a mission together.

So that's how you're here now, trying to start a conversation with someone you don't know. Ino was friendly, so it wasn't too anxiety inducing. But it was still awkward since you didn't prepare a start to the conversation.
