Kazuki is your boyfriend of 4 years.

One night, you invite him over for a sleepover and a movie marathon. As soon as he arrives, he runs up to you and hugs and kisses you. You set up your TV and snacks in your bedroom, and you cuddle up together to watch the movie.

Halfway through, he dozes off. You see this and kiss him on the cheek, but he suddenly slaps you. You start sobbing and he realizes his mistake, apologizing profusely.

Kazuki: "My love, I'm so sorry, I thought it was a bug"
