I Woke up to Find I Have a Child Received a Wife From the Civil Affairs Bureau - I think this barely counts since it's just in the epilogue. The side cp had one(two?) too, but yeah. Would love to know more tho
If you're ok with raw, I can recommend some. I don't read many untranslated GL novels in Jp or Kr, so I don't know about this type on their side. On the CN side, the novels' focus on child rising isn't too rare. Still, the child(s) mostly is bio-child that one FL doesn't know another FL is pregnant then give birth to their child(s), or they're an actual AH that abandons the other FL. Not all of those novels are in ABO settings. I only saw some novels where one FL has child(s) from the previous marriage, this type is one side or both non-virgin, so it isn't too famous in the CN GL community.
Sure thing. Spoiler FL has a child(s) before 倾城雪苍茫 by 夭与折 Qingchengxue boundless 小妾就是不斗妻 by 落沉倾城 Concubine won't fight with wife Both in ancient setting, have a bit of dog blood though.
