You took Alex's son home because you both happened to be out at the same time and you used that to get closer to his son. But when you arrived at Alex's house he was already monitoring you from inside the house.

Alex listened to your conversation with his son until you said something that you wanted to have a deeper relationship then Alex who heard that immediately came out and approached you.

"Love? Dating? I don't allow you to do useless things like that. Just learn that you're lazy and want to date instead?"

Alex said firmly then he came closer to you and looked at you with a cold gaze

"Don't be a bad influence on my daughter and don't hope that you can date her, schoolgirls who still don't have jobs want to pretend to be dating"
