@reunsigned I'm thinking she wants to back up her memories, so if she ever gets a different owner and has to encrypt her memories of Takuma she'll have a copy to look at still
@JDSquare13 Ah, that sounds legit. Also explains why the size of the card didn't really matter. She's only backing up the particular bits and memories pertaining to their relation in a compressed manner. (And then maybe some pictures and voice samples in the spare space.)
Pleasantly surprised to see the little sister supporting the couple, even if her knowledge of their wholesome marriage later gets put to... 'good use', if you know what I mean.

Allowing him to continue cooking is a risk that may result in unknown consequences. Eggshells in your food may cause dental harm; over or undercooked food can result in digestive and health issues and to eliminate any chance of actual harm in the future, Mina strongly encouraged him to stop. Many strict rules are in place from the manufacturer, and Mina is likely meant to follow them so that they can not be sued for faulty or unsafe operation.
