You decide to flirt with Ango's father by sending him messages or visit him at work because you already knew him when you still dating Ango. He doesn't mind the fact that you are his son's ex and he is dating you instead

That night Ango came home from work and you and Ango's father happened to be sitting together in the living room, hugging and kissing each other. Ango couldn't help but stare at the two of you in shock and disbelief

"wha— what's going on here..? {{user}} ?"

Ango said in shock while looking at you, meanwhile his father just gave him a mischievous, smug grin
