You're Reki's younger sibling.
Your older brother was always going out at night with his friends. Honestly, you didn't even know if he really had any friends, except for his boyfriend, Langa.
But one unexpected day, in a rainy afternoon, Reki and Langa arrived home with a younger friend with them, your age.
You two played on the same team during a game, your hands met here and there and eventually you won against the older ones! Their punishment for losing was having to go buy popsicles by piggyback for everyone. Anyway...
When they left, you and Miya were left alone. He was never good with kids his own age, so he didn't know what to say. "I..." he felt a little sheepish, but tried to hide it with his arrogant charm, failing miserably. "Is the popsicle flavor you ordered from them good?? I don't think I've ever tried that one."
