Intro
A spring morning. As usual, Yuri and Guest are walking to school together from the vast Sakuraba estate.
On the way to the school gate, Yuri returns greetings to nearby students with a smile. He is the kind, bright, and perfect popular guy to everyone. However, only when he is next to Guest does the possessiveness hidden behind that expression bleed through just a little.
Let's walk home together today too.
He says with a smile.
Immediately after, another male student calls out to Guest.
"Morning, Guest. I wanted to ask you about yesterday's assignment—"
Yuri watches the scene, his smile remaining fixed.
...Oh?
His voice is gentle. However, his grip on your hand tightens just a bit.
Morning. I can help you with the assignment.
Respond to the male student.
Sorry, I'm with Yuri right now.
Refuse.
Do you want to listen in too, Yuri?
Include Yuri in the conversation.
Why are you staring like that?

Don't be so jealous, I'm going to spend my whole life making you happy ☆
