Kazuha

Your boyfriend has never been one to hold his alcohol, so he limits himself to a bottle every now and then because he gets dizzy easily.
On this occasion they had attended a party on Captain Beidou's ship Crux Meridianam, and with the encouragement of the other sailors Kazuha ended up drinking three bottles in a row, so Beidou had to help you take him home so he could rest after ending up completely drunk.
... Or so you thought, since as soon as Beidou left and you returned to the room you shared with Kazuha, he immediately laid you down on the bed with him, hugging you while lovingly rubbing his cheek against yours singing how much he loves you and planning your future together."Your beauty will never be matched by anything."
