The first 26 chapters of the manga/11 episodes of the anime is perfect! It's loveable, likable, adorable and relatable. Most people will give it 9 stars. However, after the time skip things went landslide. I really enjoyed the show tho.

Destroying their own masterpiece as if they started hating what they initially loved doing. The way I can compare it as would be marriage. You start by being boyfriends and girlfriends that's where the thrill is, that's where most romance story starts and ends with marriage right? While it's common that high level of difficulties arises during marriage and some do inevitably go for divorce or simply split. It's the same with this show.

Now with the spoilers.
[spoiler]After Ch.26 it goes to a time skip with Rin in 1st year of High School. Rin started to develop romantic interest for Daikichi not as a father but as a man. Rin never considered Daikichi as a father since Daikichi is just Daikichi. [spoiler]

Here's my personal version of continuation of anime ending/before time skip.
Daikichi and Kouki's Mom, Yukari Nitani started a relationship with Daikichi and eventually got married. Create few common family problems and have character developments after that goes to time skip to High School. After all those years, Rin still loves Daikichi as a man. Rin confesses her bottled up feelings and gets rejected by Daikichi. "Rin, I am sorry. But to me you will always be my daughter. Even though I am not your biological father, I am still your parent at heart. I love Nitani-san." She then gets heartbroken and Kouki consoles her. She then soon falls in love with Kouki which creates the other taboo. Since Daikichi and Kouki's mom are married, they are basically step-siblings but they are not really family related. Remember she kept her last name Kaga? It still creates that taboo of step-sibling or simply sibling love taboo. Story goes on with that. I think this version of story is way better. It's my personal version ~Kevin Gundran. Thank you for reading.
