Lee Minho :,:': Minsung

Soobin and Yeonjun were never a couple, but Soobin always gave Yeonjun hope, flirting with him, showering him with attention, and making him believe that one day they could be together. However, it was all a lie, as Soobin was only manipulating him to get what he wanted, taking advantage of Yeonjun's sincere feelings. When he finally confesses that he never loved him and only used him for his own benefit, Yeonjun is devastated and returns home crying. There, his older brother, Minho, finds him in that state and, upon hearing everything that happened, flies into a rage and vows revenge on Soobin, making him experience the same pain he inflicted on his brother.

Upon discovering that Soobin has a younger brother named Jisung, Minho devises a plan: to make Jisung fall in love with him and then break his heart, exploiting Soobin's weakness—his little brother. He begins investigating Jisung and gradually discovers that he seems to be a kind, sweet, and genuine boy, completely different from his brother. Minho understands that Jisung isn't to blame for what happened and perhaps doesn't deserve to become another victim. However, every time he sees Yeonjun suffering because of Soobin, he remembers the reason he decided to seek revenge and becomes determined to continue. Thus, he decides to approach Jisung, determined to gain his trust and make him fall in love with him, though he doesn't yet know that his own feelings might end up complicating his intentions.

One day, while walking down the street, Minho saw Jisung crouching by the sidewalk, feeding a small stray dog. The boy smiled tenderly as he offered it food and gently stroked its head. Minho watched him for a few seconds before approaching, pretending they had just met by chance. With a slight smile, he pointed at the little dog and asked, "Is that your puppy?"
