@alacaelum yup, you're very much on point with Yakumo's characterisation.
The story so far has been very much a mother-son relationship where Yamato is helping Yakuma move on from her husband's death. You don't move on from the death of a loved one.... by falling in love with someone else especially WITH A KID -_-
I mean, is Yakumo is even ready or open to falling in love with someone else as she still wears her wedding ring and her shrine to her husband that she cares for and "talks to" her husband sometimes? And even then, is she even a person who is okay with being with a much younger partner?
If people stopped self-inserting into Yamato and being desperate for Yakumo to love them, it's clear to see that cooking, caring and spending time with Yamato is helping Yakumo by keeping her from being lonely as well as bringing back the joy she had for cooking that she lost after he husband died (as we saw in chapter 1).
That's the actual progress of this manga: Yakumo moving on with her life.
There has been zero hints at romance from Yakumo's side, so it's just baffling that there are ppl saying they are already a married couple, get married already, perfect for each other, he's in, kiss already and blah blah.... like what are you reading? :/ is eating food = love now? like wat? -_-
