To You Who Swallowed a Star is a Romance Webtoon Original created by ARI; it updates every Monday. The original Korean Webtoon premiered on Naver.
When Jiu Seo moves out of her childhood friend’s mansion and into a small one-bedroom apartment, she thinks her world is ending -- that is, until she meets Hajun and Hayul, the neglected children who live downstairs. When a scouting offer comes in for Hajun to join an idol survival program, Jiu encourages him to audition, completely unaware of how it will change the trajectory of her and everyone else’s lives forever.
She is shown to be a sweet and caring person, as she helped Hajun and Hayul, despite them being complete strangers to her. She is also very pretty, as Minjun developed a huge crush on her based off of her looks. Not only that, she is smart, brave, and loyal; she would sacrifice a lot for Hajun and Hayul.
At first, Wurin appears to be a sweet and caring person, like Jiu. However, it is soon revealed that he is a stereotypical rich kid; he doesn't care about Hajun and Hayul, calling them "annoying", and refuses to allow them to come with him to visit Jiu at the hospital. Even though they beg him to take them with him, Wurin still coldly rejects Hajun and Hayul. After Jiu reveals the reason why she didn't want to come with Wurin on his trip was because of Hajun and Hayul, Wurin becomes mad enough to the point where he refuses to talk with Jiu.
