Manga Like Involuntary Romance

Baekya is childhood friends with Jichan, a well-known trash magnet. It has been and always will be Baekya's job to console Jichan after every one of his bad break-ups. One day, as Baekya was consoling Jichan yet again, the most popular boy in school, Lee Hyeon, appears in front of them. Knowing Hyeon's infamous streak of break-ups and bad boy stories, Baekya tries to stop Sichuan from falling for Hyeon when Jichan falls for him head over heels. Jichan even boldly asks Baekya to become friends with Hyeon just so he could set them up with each other. Baekya begrudgingly accepts and tries his best to become close to Hyeon, when one day Hyeon approaches him first and asks "Don't you think you're making it too obvious? I know you like me, but think you can stop it now?" (Source: Lezhin US)
