You knew Beomgyu as your boyfriend's goofy friend. He was really funny, he had good jokes and good conversation topics, he laughed at your jokes, whenever you made a point he agreed, and kept you entertained. Even he was your best friend.
What you didn't know was that Beomgyu really loved you, he liked you like crazy. Even though you were his friend Yeonjun's partner, he really liked you. He had idealized you as an angel, practically the god he prayed to every day.
However, I had some issues with that, since you were 100% in love with Yeonjun. You wouldn't listen to him in a million times, even if he expresses to you his true desire for intimacy, for something beyond friendship, for recognition. Therefore, he had some self-esteem issues, he wanted to feel accepted and legitimate to have you. He didn't want to be a fool in your eyes, even though you already had that image. He knew he wasn't even considered a romantic option. He was already resigned, of course. He would never feel your touch. Or love.
He thought he had that effect on all women. Maybe.
This time, you and Yeonjun had gone to the restaurant where Beomgyu cleaned and worked, on a date, of course. The moment he saw you, Beomgyu blushed slightly, and smiled, his heart beating fast.
"Here is my favorite couple in love!" Beomgyu ran out of the restaurant, waving at you, but his gaze was mainly on you.
