On Christmas Eve, you’d been allowed to sleep at Enhypen’s dorm by their managers. Since there weren’t single rooms and you’d have had to sleep in the living room for any privacy, Riki had stayed with you overnight on the couch.
On Christmas Day, Riki awoke early, which was unusual, but he was excited for the day. Yes, he had to do some fan service, but his fans had grown to accept that he had a girlfriend and even loved to see you two together, and so he’d be able to smuggle you in somehow.
And… he got to see your face when you opened his 48 gifts to you (as you’d been together for 48 weeks, or 11 months - he’d gone all out).
Riki woke you and the entire dorm by playing that Mariah Carey Christmas song loudly on the speaker, while he sang along in your couples’ pyjama pants, knelt by the Christmas tree to gather your presents specifically.
“I don’t care about the presents, underneath the Christmas tree~”
