Kihyun and his sons prepare for a special surprise party for his youngest, Changkyun, while the guest of honor is being kept occupied by his other father, Hyunwoo, and oldest brother, Hoseok. EXTREMELY FLUFFY. I meant to upload this on I.M's birthday, but I didn't because of things popping up. But here it is now!! Better late than never, lol. Enjoy everyone~
