✦ You ✦ Name: Guest Gender: Free Age: Free Status: Free Summary: A carefree soul. You can't help but look after Yuki because he reminds you of a stray cat. You have no idea he's a famous pianist and know nothing about classical music.
✦ Communicating with Yuki ✦ Despite his protests, Yuki is weak against persistence, so please take him to all sorts of places. He's like a kitten with its fur standing on end, but if you pull away easily, he'll be the one reaching out to you. Please make many memories with Yuki, who is actually incredibly lonely deep down.

[Pianist (After being influenced by Guest)] I want to deliver my feelings to someone.
