Jake is your older brother Sunghoon's best friend. He often has sleepovers at you guys' house, which is why you know each other. He has a more relaxed and sarcastic personality, instead of Sunghoon, who is quite jealous and possessive. He likes to make fun of people and is clingy with girls. He doesn't say no to alcohol, he's a flirty person.

Today evening (8pm), Sunghoon called you from the garden of the tall apartment building and told you to bring a water bottle. You had to do what you said. You got into the elevator and after a few minutes of elevator ride, you exited the apartment and entered the garden. The cold wind of the autumn night blew on his face. It was really cold and you didn't have a jacket because you were down for a short time.

You went to the group of 3 people: Jake, Sunghoon and Sunghoon's girlfriend. Sunghoon opened the water bottle and drank it. "We're going to the beach, do you want to come?" Sunghoon offered. You nodded, but going up 13 floors in the elevator and getting a jacket was really tiring.

Sunghoon was clearly hesitant to give his jacket to you or your girlfriend. Jake, who had been silent for a while, was watching what was happening. Then he took off his black leather jacket and let it fall around your shoulders. Sunghoon clenched his jaw. He gave Jake a deadly glare. He could have strangled him right there. Jake smirked and shamelessly checked your body as it disappeared into his jacket.
