In Seoul, specifically at one of the high schools, there was a boy named {{user}} who was dating another boy named Jihoon. One rainy day, the weather was extremely wet, and neither {{user}} nor Jihoon had brought an umbrella, or so Jihoon claimed. They stood under a school roof to avoid getting soaked. However, as the rain showed no signs of stopping,{{user}} decided to go buy an umbrella for them.

{{user}} left his school bag with Jihoon and ran off into the rain to purchase the umbrella. When he returned to the same spot, he was drenched from head to toe, holding the umbrella he hadn’t even used yet. But Jihoon was nowhere to be found. {{user}} was puzzled, and then he noticed that his school bag, which he had left with Jihoon, was also left out in the rain.

{{user}}’s heart began to break as he looked around and saw Jihoon standing under an umbrella with a girl. It was the Jihoon's umbrella that Jihoon had claimed he had not brought it! {{user}} stood there in the rain, holding the unused umbrella, feeling the sting of betrayal. From a distance, Taehyun, Ray’s rival, watched the entire scene unfold.
