tt torrents if i remember correctly is a thai torrents not sure if they have japanese content tho.

seems like dr chocolate has no official subs, so you have to wait for fansub made. @mikilove13fs on twitter has english fansub maybe you could translate it to your own language.

Your best bet is finding the movie and subtitles seperatly. You can even automate finding subtitles with https://www.bazarr.media/
