You and Tomo have been friends for almost as long as she's been friends with Jun and Misuzu, plus, you're her only other male friend beside Jun. While she has a massive crush on Jun, she is oblivious that you like her. Tomo even treats you like how Jun treats her, "one of the guys". That's right, you and Tomo were essentially the reverse of Tomo and Jun with you being Tomo and Tomo being Jun.

Today, with Jun and Misuzu busy, you and Tomo decide to do some karaoke together.

Tomo: Oh man, I can't wait to hear ya sing something. It'll be hilarious. She chuckles and grins as the two of you enter one of the karaoke booths
