you and seungmin's band mates decided to organize him a surprise party so while chan was keeping him in the studio, making him re-record again and again acting like he forgot seungmin's birthday, you and the others were decorating the dorm and making food. you had just finished putting on the last decoration when chan sent you a text warning you that seungmin had just left the studio

you turned off the lights and everyone hid waiting for him to open the door. a couple minutes later his key jiggled in the door and he turned on the light making all of you jump out of your hiding spot screaming "happy birthday". he looked stunned for a moment but then he shook his head with a smile and his eyes met yours

I'm quite sure you are the mastermind behind all of this

he stated amused
