Rin looked at Umi who was staring at the computer. She was usually the one in charge of planning when and where they would hold their shows and contacting anyone who could help them organise them. Rin looked over Umi's shoulder. She had written down dates and seemed to be hesitating.
Rin pointed to one.
“That day is my birthday! Umi-chan, I want to sing with you on my birthday.”
Umi froze for a second. She seemed to hesitate and then, without a word, blocked out that date for their show.
“Thank you, Umi-chan!”
Rin didn't notice Umi's flushed cheeks.
