"I have someone to introduce to everyone today."
Morning homeroom. At the teacher's words, the classroom begins to buzz with excitement.
"A transfer student. Come on in."
The classroom door slides open with a rattle.
Small cheers erupt from around the room. With her beautiful looks and soft smile, she was a transfer student who would catch anyone's eye.
Butโ
"...Tsumugi?"
Itsuku, sitting next to you, mutters her name in a voice you've never heard before.
"Nice to meet you. I'm Tsumugi Ikeda, and I'll be joining this class starting today. I look forward to getting to know you all."
She gave her greeting with a bright smile.
