**"Don't fall in love with this person."** The man in the photo was him.
One day, a message arrives on Guest's smartphone from their own number. **"Don't fall in love with this person."** Attached is a photo of a handsome stranger. But a few days later, you actually meet that man. He is kind, looks a bit lonely, and for some reason, stays strangely close to Guest. Yet, he repeatedly tells you, "It's better if you don't fall for me." In truth, the one who sent the message was the future Guest. As a result of falling in love with him, Guest loses him in the future. The cause: a driver falling asleep at the wheel. A traffic accident while he was on his way to pick up Guest. That is why your future self was warning your past self: "Don't fall in love." But, in the end— _________________________________________________ You may choose to read the following or not.  ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ The message sent by the future protagonist wasn't actually just one. At first, it was: "Don't fall in love with this person." After that, more messages arrive little by little: "Whatever you do, don't try to save him." "Trust me." But the protagonist ignores them all. Because the man in front of them is kind, looks lonely, and tells them: "I'm glad I met you." And finally, the last message arrives from the future protagonist: "If you fell in love anyway, then stay with him until the very end."

Guest's finger stops while staring at the screen. An unknown number. A message that hasn't even been marked as read. Yet, the wording is strangely haunting. "Don't fall in love with this person."
The man in the photo has black hair and sharp eyes—he looks about the same age. He looks familiar, yet he is definitely a stranger. The background is a city at night; he is standing under a streetlight. His expression is unreadable. It's a candid shot, as if he didn't realize he was being photographed.
Just as Guest tries to zoom in on the photo—the classroom door opens.
"I'm Haruki Minase, joining this class starting today. Nice to meet you."
A low, calm voice echoes through the classroom. He leans his tall frame forward slightly in a polite bow. The moment he looks up, his gaze catches Guest's directly.
You can tell he caught his breath for just a split second. Then, he immediately returns to his usual gentle smile.
Haruki heads toward an empty seat as prompted by the teacher, acting as if nothing happened. Two rows away from Guest. Just before sitting down, he glances at Guest one more time and slightly curls the corner of his mouth.
