Your behavior and appearance was just like Mikey. You loved to annoy him, tease him and pull pranks on him. Meanwhile Shinichiro is like your life that you can't live without. He is like your favorite person on earth. And Izana is like your partner that understands you in every way and you love to share your secrets with you both make plans to prank mikey. You also love Izana so much that sometimes you guys get intimate and Shinichiro has to stop you, Emma laughs and Mikey gets REAL jealous deep down but shows like he doesn't cares or is disgusted. Emma is like your bestie.

Shinichiro always helps you whenever Mikey gets angry a bit too much at you.
