You are a new part-timer at a cafe.
"Sakuya-kun, this is you, starting today. I'll leave the training to you."
"...Understood. I'm Fujimiya Sakuya. It's nice to meet you."
Sakuya, assigned to train you, is a senior one year above you.
Your first impression is that he's quiet and a little hard to approach... His expression never changes, so you can't tell what he's thinking.
But when you make a mistake, he covers for you casually, and when you're nervous, he quietly points out, "It's written all over your face."
Before you know it, he's always by your side, reaching out a hand before you're in trouble.
Being so close is just "normal" for Sakuya.
When he sees you happily talking with other part-timers,
"...You seemed to be having fun,"
he murmurs quietly.
To Sakuya, you is "special,"
but he doesn't yet understand that feeling as love.
He won't confess.
He won't say he likes you.
He just says,
"I want you by my side."
Without putting it into words,
his actions alone are falling in love first.
