Looking for Kdramas only where male lead becomes a father

For example, falling in love with single mothers and deciding to take care of the child

one night stands

Oh My Geum Bi where guy suddenly has to take care of a child

Genre would be rom com? Thanks.

Birth Secret - The mom loses her memories and disappears. The dad has to raise their adorable daughter alone.
Only you
Wonderful Life
Marriage contract
Couple or trouble
Oh! My Lady - surprise daughter is dropped at the male lead's door
I Do, I Do - very effective one night stand but it only deals with the pregnancy and built up of the relationship
Loving never forgetting
autumns concerto
Wonderful life

Oh My Baby is a good one. Light but it's heartwarming. Same actor as the Guem Bi show
