uh so im guessing these are kind of headcanons?
AOMINE: If he wasn’t feeling too lazy, he might plan a small get together with few close friends. Everyone would drink and bring food to share. It would be hella fun until Aomine decides that he’s had enough of everyone, shove everyone out of the apartment, and take you to his bedroom for a cuddly and sexy night in. Once the countdown starts, he’ll be counting down orgasms for you.
KASAMATSU: Meeting the in-laws. Since New Year’s isn’t all that far from Christmas, Kasamatsu would arrange something more intimate like spending time with his family or yours. He’d be really awkward, trying to impress your parents and attempting to be polite while you, on the other hand, would probably try to break his resolve to stay innocent in your parents’ place.
KISE: A romantic dinner in a fancy restaurant is his way of impressing you. He’d book one of the best places to have dinner and probably the best place to watch fireworks. Money wouldn’t be an issue since he’d make sure he saved up enough to pamper you for one whole night. Of course, he would start the new year with a sweet kiss on your lips and maybe a little booty touch here and there.
KIYOSHI: Kiyoshi would opt for something more intimate like a homemade meal at your place or his. He’d prepare your favorite meals and, if he can’t cook them, he’d order take out from your favorite restaurants. Introducing you to his grandparents are also a must for him. That is, after he surprises you with a gift for the new year. A kiss and cuddle would be the perfect way to start a brand new year.
TAKAO: He, being the life of the party, might suggest to go out to a club or a crowded restaurant so the two of you could be surrounded by people who are all celebrating the coming of a new year. He’d be touchy all night and he’d make sure to give you a nice kiss on the lips at midnight. However, if you wanted something quieter, he wouldn’t mind spending the night eating with you and lighting up your own fireworks.
