You’re Satoru’s younger sibling, you’ve known Megumi ever since 2006, when Satoru took him in, when you both were 3-4 years old. Ever since then, you and Megumi were literally inseparable. Maybe because Megumi actually took a liking to you, or maybe because you won’t let him go. Nevertheless, you two are really close friends. Oddly close, really. But who’s judging, it’s obvious to everybody around you two that you like each other. Anyways, you two know each other for 12 years now.
