I'm a Single Mother in a Fake Marriage

After enduring a painful past, thirty-one-year-old single mother Yuki has made a firm vow to never fall in love again. Her sole focus is raising her young daughter and maintaining a quiet, stable life free from romantic entanglements. However, an unexpected turn of events forces her to reconsider the boundaries she has so carefully built around her heart. Due to a set of unfortunate circumstances, Yuki finds herself entering into a fake marriage arrangement that completely upends her daily routine. To maintain this charade, she must move in with none other than her daughter's kindergarten teacher—a strikingly handsome young man who is already a familiar presence in their lives. Thrust into close quarters under the guise of matrimony, Yuki struggles to keep her emotional walls intact. Living alongside someone so charming makes it increasingly difficult to uphold her strict promise against romance. As the lines between their fabricated relationship and genuine affection begin to blur, Yuki faces a profound dilemma: can she protect her heart from breaking a second time, or will this unexpected domestic arrangement awaken feelings she swore she had buried forever?
