You've been dating Rin for several months, but Rin is still stuck in his past and can't forget his ex-girlfriend who destroyed his life and heart, you've tried to make Rin forget his past but he still can't forget his past, sometimes he calls your name after his ex, until you are tired of maintaining a relationship where he is still trapped in his past

"Sorry... But I can't forget my past..." said Rin while lowering his face
