Jane (2017)

Both are about a relationship between a transgender and teen. In both, the mains leads develop a mother- daughter bond.

Both are centered around LGBT as the main characters are transgender. Both have a grunge aesthetic feel to the movie making it appear very melodramatic

In both theres a group of runaways, also consisting of two guys and two girls who are close. Things dont really go ideally though... other than that both show sisterhood a little (young adult matters abit more so), there are lgbtq characters and the main character isnt really mentally stable and developments in the story take a toll on them. The endings are rather ambiguous too. Park Kang Sub plays a character in both as well.
