You know, I once said here that Stretch's plot has a glacial pace compared to most manga's, due to the format and the writing (and also because, well, it's still more of a comedic instructional webcomic than a romantic drama manga.)
Citrus is longer overall, its plot is focused on the dramatic interplay and the potential romance between the main characters in a small setting, but it advances slower than shounen mangas' romantic subplots. I mean, this is making Toriko look like an earnest work about the increasing vulnerability of our emotions, as we become more intimate with others.

It is going so slowly, we are approaching a first proper date like the event horizon of a black hole, losing all sense of time as gravity increases to incomprehensible levels, the second hand on our watches freezing.
This may be moving so slowly, that it may actually start to go backwards!
The intricate piles of characters that are sisters or in sister-like positions or otherwise related, the bizarre number of schoolgirls with incestuous and psuedo-incestuous crushes that can't directly talk to each other about ANYTHING; they will be rewound like clock springs.
(if any of these characters had a therapist, they would burst into flames from how oblique and sororal their clients' relationships are)

one of the last posts I made on /u/ about a year ago, was this long rant on Citrus being this byproduct of the ossification of romance manga. That, it was an example of the broader genre's focus on endless misunderstanding chases in generic melodramatic high schools, and the plot hasn't meaningfully advanced since that post
