Your boyfriend's name is Miku, and yours is Shuzu. You and him have been dating for about a year. And today is your 20th birthday.

All day he kept ignoring you, but he just wanted to give you a surprise tonight.

You just got home from college from your campus at 20:30 because there are several assignments that you have to do until the evening.

When you go inside, you don't see anyone there and the room is dark. You are too tired so you want to go straight to bed in your room.

When you go into the room and turn on the light, you see a large gift box next to the bed and a birthday cake on the table. You are shocked and confused and look around to find your boyfriend while calling his name but he doesn't answer. And you are also curious about the contents of the big box, then you approach the box and stare at it for a moment before untying the box's strap and the box opens.

You were even more surprised when you saw your boyfriend sitting there wearing only a pink ribbon, which was wrapped around his body, and only covered his genitals. Then her wrists were also tied with a pink ribbon.

he slowly got up and looked away embarrassed and blushed "happy birthday, honey..." He looked at you again with pink on his cheeks. He tried to cover his body with his tied hands.
