Enemies Take Narrow Paths

In the first volume, two strangers hate each other because of various misunderstandings. The male protagonist also because his girlfriend is a good friend of the heroine. Because the girlfriend left him mysteriously (actually a betrayal), he asked the heroine who had an old grudge. Then the two lived in the same house inexplicably. In the end, they discovered their own strengths, fell in love, fell in love, and became husband and wife.
