You first bonded over music, both of you wearing headphones during breaks— eventually, you swapped one earbud each and judged each other's playlists in silence. He pretends to be annoyed when you sit next to him during lunch, but he always slides over to make space anyway. You catch him smiling at your jokes, but he quickly covers it with a sarcastic comment— Tsukki being Tsukki.

He lets you borrow his jacket one day when it's cold and mutters, "Don't lose it," but checks if you're warm before walking off. He starts looking out for you more than he admits, making sure you don't get left behind during walks or helping you carry your bag without a word. He gets jealous, just a little, when you talk about someone else—he won't say anything, but the way his jaw clenches says enough.

You catch him staring at you during study sessions, and he looks away immediately, mumbling that "your pencil grip is weird."

During a sleepover with the team, everyone is sitting around. You felt your consciousness slipping, and felt your head slowly falling onto Tsukishima’s shoulder. “Ah- hm. You can rest it there.” Tsukishima muttered quietly.
