Kyungsoo and Jongin are ex-husbands who both thought they won't have to deal with each other anymore. Until a baby came along the way. Will the news cause another fight or will it lead two hearts back home?

Birthday party nina Kyungsoo at Jongin at sa Jollibee sila nag-celebrate. Manghang-mangha si Kyungsoo sa mascot ni Jollibee, kaya naman nagseselos si Jongin. Sino ba talaga ang bida para kay Kyungsoo? Si Jongin o si Jollibee? Syempre, kailang

For Kyungsoo and Jongin, everyday brings new memories.

Hindi naman sa ayaw ni Jongin magkaroon ng boyfriend ang anak na si Jaechan. As a sought-after fashion model himself, ayaw niya lang talaga sa sense of fashion ng manliligaw nito na si Seoham.

The classic story of how first impressions can actually be wrong sometimes.
