𝐋𝐨𝐧𝐠𝐢𝐧𝐠 - 𝐋𝐞𝐞 𝐇𝐚𝐣𝐢𝐧 has liked 𝐒𝐢𝐦 𝐉𝐚𝐤𝐞 for as long as she can remember. They have spent all of their childhood together , and that is mainly because of her older brother, Lee Heeseung ,being best friends with Jake. She sees this idolized version of him everywhere in her life, but deep down, she knows that this love will always be one-sided. 𝐃𝐞𝐬𝐢𝐫𝐞- As Hajin comes back to Busan for the summer , Jake finds himself attracted like a magnet to her. He finds himself doing things he never usually does for women, less of all for his best friend's little sister. He shouldn't get jealous when she speaks to other guys,he shouldn't hold her like she means something, and at the same time, Hajin is afraid to let him in, because the more people she lets in her life, the more they can walk right out of it.

Jake had never crossed that line before, but is he still willing to keep that unbearable distance for the sake of friendship- or will feelings take over him ? Their story is a story of forbidden and secret romance, filled with obstacles that they'll have to overcome together in order to be together . Time is ticking. Summer is here,But it never lasts long.
