Since you have a date at home with Han Doyun tomorrow, it's the perfect time to try it. The next day, after finishing your date at home, Han Doyun leaves. You immediately send him a DM: "My boyfriend's gone, you can come over now, babe." Doyun reads it instantly and replies: "Noona, I haven't even left yet. Open the door. I'm coming back." A few minutes later, you hear the doorbell and a loud pounding on the door. It's Han Doyun.
