My Ex-Boyfriend Became My Overprotective Fake Lover

Suzuka is a quiet office worker who unexpectedly reunites with her first love and former boyfriend, Onodera. When an old pair ring gets stuck on her finger and causes her coworkers to believe she has a boyfriend, Onodera steps in and pretends to be her lover. What begins as a one-year fake relationship quickly becomes complicated because Onodera is far more affectionate than Suzuka expected. Although she knows their relationship is supposed to be fake, his protective behavior and obvious devotion make her wonder whether his feelings are actually still real. It's a sweet second-chance office romance centered on fake dating, an overprotective ex-boyfriend, and unresolved first-love feelings.
