Daraku Kazoku-ron
Ririko dies young and leaves behind her 6 year old daughter, but she was just as irresponsible in death as she was in life and tells Meguru that her father is likely either Touma or Sentarou (probably) so just pick one of them to be her dad. And never get a DNA test! And so the three of them start living together, and bring up a lot of old memories, mostly for Sentarou. I love everything about this. Meguru is such a sassy deadpan girl
Tabun Korekara Ai no Hibi
After giving up on his dreams of being a mangaka, Aki reencounters his high school friend who always encouraged him in his work. But they get a lot closer after Aki loses his house and job in one day and moves in with Kuma and his two kids. It also seems that Kuma has finally realized that he had a lot more feelings than just admiration for Aki after all these years
Futari de Papa Hajimemashita
The kid is the cutest part of this, the relationship is just meh, but Tsumu is worth all five stars
Take to Kota to Aoto
The child is so angry and stubborn, not the perfect little angels you tend to see. It was cute. The whole family dynamic is very fun and heartwarming. Grandma is obviously called old hag and Take is rarely ever called papa.
Everyday is a Good Day
