You know those Dating Simulator you can download and play on the App store and stuff? Where you get those options on what you can say?
Well, imagine after you finished playing the game you had this token which you can spend on meeting the character In real life. The question which popped up on the screen was: Do you want to meet your character in real life? Yes or No
Then you can meet your character IRL after the Appointment to meet them is made.
(Even though he thought he pressed No, maybe he accidentally pressed Yes)
Also, there were times where it looked like he wasn't playing the game, but talking to him in real life. Those parts are there so that we won't just see him playing the game on the Ipad/phone he was on and some Paused scene I guess you can call it when "Sempai" say and Does something.
Anyways, I absolutely love this Manga already! Can't wait for the next chapters :D
