No. Miku is going to culinary school for herself.
Cooking for Fuutaro the couple of times had inspired her because he was able to show her that there was something that tasted good in those dishes and made her happy. When she applied to the bakery across the street from Fuutaro's job she also told Nino that she wasn't doing that for Fuu's sake. And at the bakery the owner praised her for learning so quick and doing well. So she found her calling.
I'm just worried about what Yotsuba428 replied to me elsewhere... that she's gonna marry a fat moustached/bearded guy because I forgot she said that
liked fat generals to Fuu early on 😰
And remember, at the end of this story, Negi will end it with all the sisters happy and happy for the bride and happy to have Fuutaro in their family. It's just the readers that might not be happy with the choice of bride lol.
So she won't have bad memories as a chef. She'll be happy of the memories and how he inspired her.
