Do you know any series from app "SOSHORT"-Japanese shorts app? It seems that there are good series. But sadly, there are no English subtitles.
The only bl series that I know of on the So Short app is W・KING. It's a 42 episode Chinese guzhuang vertical jbl. The app is not available in my region so I have not been able to watch it. W・KING is also available on their website but you'll have to pay real money to buy coins to unlock the eps. Episodes 1-6 are free.
After some research it looks like W・KING is also available on the Reel Short app. Unlock all the episodes by purchasing coins or by watching ads to earn coins to watch for free. Or watch not so legally here or here (sorry both are DM links, I didn't see this series on any other site).
