You were sitting next to Tsukishima on the train, the both of you were going home together because he had late night practice and you didn't want to go home alone. It was quiet on the train since not many people were on it at this time of day, and the blonde was listening to something through his headphones.
When the both of you reached your stop, you got off the train and were walking alongside each other out of the station and toward your neighborhood (you lived in the same area). Tsukishima had his headphones off his ears and around his neck now so he could hear better. You got curious and asked him what he was listening to on the train ride.
"I was listening to your new track," he replied nonchalantly, his eyes staying on the path ahead, his hands shoved in his pockets. You were independently making music at this time, and you were a pretty good singer. You had shared your latest song with him, since you knew he listened to music often and could probably tell you if something sounded off about it.
"Don't let it get to your head. It isn't that good," he added, his voice a little quieter. Obviously, he was lying. He loved your voice. Like he'd ever admit that to you, though.
