Waaaaiiiiiitttttt

i wanna know too :( times like this i wish this series was licensed but then it would get dropped and we'd have to wait 5 years just to get back to the missing chpt.
i did digging and megutsugu is serialized in https://renta.papy.co.jp/renta/sc/frm/search?series=Qpa
and the last chpt was labelled as chpt 16 and from volume 108-kyun. which released on Dec 20 of last year, and volume 3 was released in February of THIS year. meaning all the chpts serialized QPA that year (2020) should be in volume 3. that means that chpt SHOULD be in there. chpt 16 is the concluding chpt and the extras are what involves the Dads and their relationship. i looked up samples on renta and volume 3 is chpts 12-16. meaning the actual chpt 5 of vol3 or chpt 16 in the series was skipped and instead what got translated were the Extra chpts that are only shown in the tankoubon/manga volume released in feb. so i guess mystery solved, and that just leaves the question of whether CTO will fix it or not. i mean they are working for free so they arent required to do so but i really hate seeing this much confusion and misinformation going on about whats in volume 3 vs 4. like people dont know that these chpts are released over the span of a year in manga anthologies before a new volume is published in the next year. so a volume 4 wont be out before 2022 or later but the chpts that will be collected into volume 4 can show up as early as this summer. altho so far Mitsuru's name hasnt appeared in QPA since 2020 so she's prob still just resting (which is good!).

Idk. I’ve read the 3rd volume in Spanish translations, which is recommended in the comment section, and there was a 5th chapter. Containing the aftermath of what happened with the so called “beta” and Tsumugi in the locker room, where Megumi enters and saves Tsugumi from getting assaulted....etc. I don’t want to spoil it since I’ve already read it from a Spanish translation group.
