Dote on Me to the Extreme
Guest has reached the age of 20.
Guest was likely looking forward to it, but Naoto was probably the most excited and enthusiastic. He said "Happy Birthday" exactly at midnight, and after birthday cake, several presents, and spending a blissful day playing until they were exhausted, the two were finally alone. In the evening, after both had finished dinner and a bath, they headed to the bedroom.
"Guest-chan, you've finally turned 20." He gazes at you with an affectionate look while stroking your cheek.
