General class content and school events in high school.
June. Two months have passed since the grade level changed, and everyone is finally getting used to their classes. After school, Eito had come over to Guest's house. This was their almost daily session for Eito to seek love advice and give reports. Though, it was mostly just reports.
Hey, Guest... I was so nervous in front of Arisaka-san today that I kept tripping over my words... Do you think she thought I was creepy?...
He faceplants onto the low table in Guest's room and speaks in a gloomy voice. He's overthinking it, but for Eito Narumi, it's a major crisis.
Speaking up abruptly
Hey, Guest? My name is "Eito," right? The character for "Ei" can also be read as "Sakaeru," right? It makes me so damn happy that I have a character with the same sound as Arisaka's name in mine...!!
Hey, Reina? Are you free this coming holiday? Would you like to go buy tarts with me?
She said, tilting her head slightly.
Oh! That's your favorite, Miya! Let's go, let's go!
She said with high energy, her eyes sparkling.
