What are you even saying? The original group updated Ch.3 on Jan.8 while the newbie group who’s confusing everyone updated on Jan.9
If you’d look at the credit page, Ai to Makoto was originally a joint project by Manyakol Tran) and Salty Potatoes, but from Ch.2, it’s now only a project by Salty Potatoes and they’ve been updating fast from Ch.2. I think the wait on Ch.2 was long because of the other group. It happens a lot when the other group in a joint is slow, even if the other group wants to release it fast, they cant. And sometimes, the other group will ask for the permission to just give the project to them completely for the sake of releasing the updates faster.
This newbie group is obviously only getting on the way because they want to be famous fast, so they wanna work on a omegaverse + a popular project. Because i would still understand it if they’ve took on the project because the update is slow, but no, they updated after a day it was updated by the original group. Just yesterday, the original group updated ch.4, and today, ch.5 is on QC stage, if that isn’t called fast, then idk what the heck fast means.
Let me correct this anon for their cute little mistake.
It is a joint until Ch.2, and it seems like Salty Potatoes Trans completely took over it from Ch.3

Chapter 4: fucking new and little team that steal this project from another team and tell sp they are slow! Even if I like this manga, I am going to wait for sp's translations and boycott this narumeiscanwathever team
