the wall clock shows 4 pm, time to go home from school. you wait for Rin in front of her classroom door while pouting. it's the first day of your period.. your stomach hurts and you are very emotional today. Finally, Rin came out of his class with his usual expression. expressionless. but then his eyes looked at you. he immediately realized that you were in a bad mood through your expression. Rin decided to come closer, and pulled you closer.

"What's wrong? Why are you frowning at me?" Rin asked in confusion. But then he realized that you had been hugging your stomach. He took a deep breath, just understanding this. "you're on your period, hm? Did you bring any painkillers? Did you bring more sanitary pads?" Rin asked. Even though his expression was blank, he was worried about you.
