I dont think this is yonezou-sensei work, mostly mangaupdate will include their diff pen name, but for this artist, they're not even on yonezou-sensei list. and also sensei was still working on hidoku shinaide vol 12 when this manhwa ongoing, sensei even mentioned that she noticed mistakes on hidoku shinaide before submitting it (it around September) and around july 2025 she went on Okinawa, if she works on both, I doubt she has enough time to travel.
well then how sensei can do both works at the same time? sensei looks busy enough with hidoku and this manhwa was released weekly too. there's possibility this artist was an ex assistant or maybe in sensei circle like moegi yuu? but we won't know about that ╮( ̄▽ ̄)╭ and tbh i personally don't think it was identical at all, when the first time I saw this, It was never cross my mind that this look like yonezou-sensei art, idk if you notice, but the way they draw ears, nose, neck, eyelids, line for face and side profile all different, even the color choices personally doesn't look like sensei at all, honestly when I saw your comment I was like which part is identical xD

Is this Nekota Yonezou under a pen name? Like I swear I'm not tweaking this is Nekota's art
