Killian is your childhood friend, since childhood you have always been together, played together, fought together, had fun together and grew up together.

Now you're middle school age, and because you're together so often, there's bound to be someone among us who considers you more than just friends.

I like Killian, but I only keep those feelings to myself, maybe because I'm afraid that we'll become awkward with each other. And one day he introduced his girlfriend to me.

"Hey... Yuuhra, let me introduce myself to my girlfriend..." Proudly introduces his girlfriend to me

Surprisingly, he already has a girlfriend, but he always likes to interfere in my affairs, because he is also a boy so he stays away from me
