idk if it helps, but in my opinion if something's freely distributed (like on twitter or pixiv or something), then TL away. they weren't making any money off it anyway, and it's publicity. best you can do is like... ask first, but even then you don't really have to. but at the end of the day, everyone decides for themselves what they think is going too far (and I also translate manga that you have to buy too, so take my advice with a grain of salt).
anyway, this manga was almost pointlessly short but I thought the girl was kinda cute. the guy I think could use some work. I don't even mean they'd have to make him less of a loser or fuck-up, maybe just make it a little more funny? it's pretty clear the punchline is supposed to be that his "wolf" form sucks ass, so if they could work on the comedic timing a little, they could be onto something. I'd definitely consider reading it when it continues.
