kek, i actually only found out about it while browsing r/manga/new/ 3 years ago from another cultured SL requester that is u/casualphilosopher1
extended answer:
so i went to the yanmaga website that was linked in the reddit post and i was like "wao, this is a hidden gem, how come no one is translating it when the other yanmaga manga are being translated" (like Kanojo no Tomodachi (JURA) and Toshishita no Senpai iirc at the time). i'm then like "i need to download this and hope that it gets picked up in the future by some cultured scanlator". i'm also somewhat of a data hoarder so i felt the need to archive it at least but i digress
only the first few (and last few?) chapters could be read for free and yanmaga jp is a japanese website so i can't understand how the site works so i first checked various raw manga aggregators whether they had them but nope. not even dlraw.to has it. i only found the one-shot mentioned in the last page of chapter 1 translation which was just chapter 1 but in black and white but i don't remember which website that was
but i really wanted to rip the other chapters too so i made a free account and found out that yanmaga has a system that gives you daily tokens when you login and certain chapters become unlockable by tokens depending on the date. it was still ongoing at the time and i was lucky enough to get to rip them all over the weeks kek. i think i used like 3 or so free accounts bc the tokens were too slow to replenish
