The top works in FnB and bottom wants romantic gestures but never communicates it. On bottoms bday, top gets a cake for bottom but claims it was because his restaurant had extra even though he actually purposefully went to buy cake to celebrate.
Whole series of misunderstandings where bottom breaks up with top but they still live together and its currently on 2nd volume where the top bought a restaurant and owns it now
Manga where they were reborn as villains and they identify each other using "how are you?" "Fine thank you"

Is there any way to check how many chapters of a manga I've read in a day or in 1 sitting?
it will depending on the manga or manhwa. mangas are very packed and has many conversation. but manhwa or webtoons have less conversation and easy to read(one action one panel like thing) and every author has different sized manga chapter so it will be difficult.
maybe start reading one manga that has many chapters and see where you are until the end.
