Serious question, what's wrong with she can't drink alcohol and his family's reaction to it? Do they think she's preganate or something?
Yes, MC's mom immediately thought of pregnancy, and MC (and sis) instantly realized she thought of it, so MC hurriedly corrected her misunderstanding.
MC's mom's
instant reaction, and them (and touko) picking up on it suggests this is an important/sensitive topic for MC's mom - possibly related to her husband (MC's dad) dying early.
Accurate but for a "reason", it's sub-optimal
so by your definition: sub-optimal = slow, this is too much of joke , especially since there are lots of 'optimal' one series mangaka who produce slower than this mangaka.
to have multiple series ongoing like that and skill issue
there is literally nothing to back this up, in fact there are lots of super popular (and super fast) mangaka who
has made more than one manga at the same time (akasaka aka, hiro mashima, urasawa naoki, etc.)
P.S.: first one's ok,second one(and this)...😬
...so you came here reading a series you don't like , just to criticize the author 😬
no point in debating with you further then
