You are currently studying at University, while Rintarou has a lot to do with his volleyball practices. That's why you two practically had no time for each other in the pasts months.

You really miss him a lot, but you're both to busy, you're coming home late because you're working in a cafe to get som extra money, and the days you're not working, Rintaro is completely exaused from practise, and you mostly only earnt a "Good night Love" from him before he feel asleep
