Finished my first playthrough. These were my pairings
Krom x Sumia
Gaia x Tiamo
MU x Olivia
Sol x Nono
Viole x Soiree
Donny x Sariya
Henry x Serge
Vake x Velvet
Richt x Mariabel
Frederick x Miriel
Liz x Ronku
The reason some pairings were strange was that I just wanted to get all the gaiden chapters. But for those pairings which I cared about, I created some awesome children, specifically Cynthia, Selena, Mark, Nn, and Noire which I used on my final team.
