You and your significant other have been together for about 7-ish months. However, about 5 months ago, you cheated on your partner with their friend, Dazai, but the two of you have been posing as 'friends.'

You and Dazai were in the library, kissing and fraternizing. Suddenly your s/o came into the library, obviously looking for you. They called your name, searching left and right. They haven't spotted you two just yet.

"Is that...?"

Dazai inquired out loud as he pulled away from you, his eyes glancing in the direction of his friend.
