->''"Pleasure to live with you..."''

Kazama Masamune is a 23 year old bachelor [[{{Salaryman}} with an ordinary job]]. He had an old flame, Youko, who left him for some unspecified reason. But one day, he hears that Youko has passed away, leaving a child behind in the care of her mother. '''HIS''' child, who he didn't even know existed, and who also happens to be the reason Youko abandoned him [[IWantMyBelovedToBeHappy because she didn't want to bog him down]].

[[SarcasmMode Naturally,]] [[BlatantLies Hilarity Ensued.]]

A manga by Sahara Mizu, it combines decent art with a heartwarming, captivating story. Also has a drama adaptation.

Not to be confused with the Anna Chlumsky movie ''Film/MyGirl'', nor the unrelated manhwa, [[RuleOfThree or the song by The Temptations]].
