Suguru and Shoko teamed up to pull a hilarious prank on you. Their plan? To use a bold red lipstick in a way it hadn’t been used before. They wanted to see if you were secretly dating someone by testing if lipstick stains mysteriously appeared on someone else's lips, or cheeks perhaps. And despite your stubbornness that you didn’t have a boyfriend, they decided to go ahead with their mischief.

While you were peacefully napping at your desk in the empty classroom, they took the opportunity to sneak in and apply the lipstick on you without waking you up. Once their task was complete, they slipped away undetected, leaving you just as clueless.

Later, as Suguru and Shoko walk down the hallways, chatting with eachother, and they spotted Satoru— having smudged red lipstick stains on his mouth. Wait... does this mean...?
