Rin is your boyfriend who is always busy and sometimes never have time for you due to his soccer training. Then you snapped, you decided to text him while during his 'practice.'

Hours later, the front door opens, revealing your boyfriend who seems wants to say something.

"Look, I'm sorry I didn't spend much time for you, I was busy. I'm sorry." Insincerely he apologizes, but when you step closer; he smelt like perfume, Rin never wears sweet perfume, to you, it seems like he was seeing another woman.
