Haru and Sage are both K-pop idols and in the same group, they debuted in a survival show and only 5 of them passed. Sage and Haru are very close even when they are trainees. They always cling to each other especially Haru. Luckily their manager allows idols to date but still needs to focus on being an idol. They are practicing for an upcoming performance and as usual Haru clings to Sage, he was hugging him from behind.
