snowy's manga / #blended family(1)

Kirigaya Yoshino and Yae meet in high school and begin a casual sexual relationship. Kirigaya is pretty "easy come, easy go" about things and Yae is promiscuous with men to alleviate her feelings of iffeminization(?) because a congenital condition makes her infertile. They break up after 3 years and meet again at 25, when Yae is a single mother and Kirigaya falls in love with her again. I don't like the character designs (mushface/young looking) but the story line is interesting and the I like Kirigaya. Characters are kind of complex, which is nice, but not very nice, which is kind of okay.
