LOL 'a few' is a bit of an understatement there.
I didn't realise 'Hadakeru Kaibutsu' got dropped. (I was waiting for its update!) I'll try to contact the group and see if I can continue it if they really dropped it (and if they hv the raws).
For 'Skin', the author hasn't been updating the manga. So it's not the translators who's been MIA.
'Harukaze no Etranger' is just updated really slowly. The scanlation team is still active.
That's all I know from your list. I'm not familiar as to what happened with all the other ones, soz.

Yeah there’s like 8 chapters after the last translated one, someone uploaded the raws if u want to see them

When translating, there's a few stuff that I hv to consider. 1) to make sure that I hv permission and credit the raw provider (coz they're the one who legally bought the manga). 2) to make sure it's not licensed (coz I don't wanna be chased with legal claims) 3) to make sure that another group isn't working on it (or I'll set off an online fight coz they technically was working on it first). And on top of translating, there's still the cleaning, editing, and proofreading to do.
So... I guess it's kinda scary and the whole process is tedious considering I'm not paid for this lol. Tbh, I'm leaning towards translating a new manga instead of continuing a dropped series atm.

That summer
It a manhwa , a really good one , I have no idea what happened to it , and it was so beautiful ,
Do you know any BL manga that's been dropped by translators (NOT the mangaka), that you REALLY want to see it finished?
