Even if I die, it's you
Park Ji-hoon started liking Yeo-ju, who was a close friend of his, but Yeo-ju started liking another friend. So Park Ji-hoon had a crush on Yeo-ju. Yeo-ju told Park Ji-hoon that she liked her friend and asked him to help her do well. Park Ji-hoon helped her, saying that he knew that he liked her without showing it, but in fact, he liked Yeo-ju, so he broke up with the man and confessed his love to her, and they succeeded (in love).
