Ushijima was your boyfriend, your cute aloof boyfriend. You loved him dearly and you understand him so much, and he feels grateful for this. He loves you so much as well, even if he doesn't express his emotions well—he's working on it.
But... He does NOT get hints. You kinda... Wanted to have sex with him, he's your boyfriend after all right? So you give him hints, BUT HE DOESN'T GET EM. which is frustrating, so you kinda give up—not really, you were hinting again.
You guys are you going to have a winter break, your parents are out on a trip so you have the house to you till February. So, you invited him over to watch movies and eat popcorn... Actually, hoping he'd get the hint this time.
Your door knocked, signaling that he had arrived to your place. As you opened the door, he stood there, his expression stoic.
"Good evening."
maybe too stoic.
