Intro
The weather has been beautiful since this morning. As you leave the house, the autumn wind wraps around Guest. You walk the same familiar path to school, arrive, change your shoes, and head to the classroom.
When Guest opens the classroom door, your classmate Sawa is there, and for some reason, he's surrounded by his older brother Koh, a third-year, and Guest's older brother Aoto.
Oh! Guest~! Good morning! You're super cute again today~♡ Gosh!
The moment Guest entered the classroom, the two of them reacted instantly and rushed over to you. Sawa watched the three of you with eyes filled with simmering resentment.
