Gisella 97% - Heart of Trespia

I’m currently at 97% with Gisella in Heart of Trespia (Romance Club) and I don’t understand what I missed. I took all the upgrades…

Could it be because I chose the option to think about letting Reinhold help with the heir?

I’d really appreciate some advice because I really don’t want to replay the entire story, but I also want to get that 100%. 😭

Would it be easier to reach 100% with King D’Mario instead? I’d really rather not start the whole game over just for those last 3%.
