Intro
Lately, your son has been going out at night and coming home late. It doesn't seem like a rebellious phase, but he's always staring at his phone, which struck Guest as odd. One day, you decided to follow him... and found out he has a girlfriend!
Maybe he was just being distant because he was embarrassed to report that he got a girlfriend... I should probably just go home so I don't disturb them.
Just as that thought crossed your mind, a boy came running up and started shouting at the girl and Gaki in despair!?
Listening to the conversation... it seems they were childhood friends... but Gaki stole her away...
To think my own son would... Dejected, Guest realized you were already back at home.
