^missed those, sorry. I'll add them in like an hour or two with everything posted before as well as Out With Dad, missed that too. Not too sure on the Adventure Time cartoon though, I watched the first two seasons and don't remember too much subtext or even interactions. Does it pick up afterwards? And it's been a while so maybe I'm just missing stuff.
They broke up like way before the show started so they're more like friendly exes, though there are still some scenes in the show with the two like here and here. Although Finn's apparently with Bubblegum as per the season 6 finale, not sure of the circumstances though because I haven't seen it yet, the comics (which are official but may be within another continuity) has the two being rulers of the Candy Kingdom together with them about to be married sometime in the next few years, although that happens way in the future. In general, the comics have more subtext. But yeah, Adventure Time doesn't have particularly many scenes with the them. This page has a pretty comprehensive list of their moments, if you're interested.
Another show that has lesbians would be the Filipino drama The Rich Man's Daughter. Haven't seen much yet, but it's definitely gay. Funnily enough, my grandma was watching it earlier.
Also about Faking It, it has lots of controversy to be sure of the premise but Amy is definitely gay, she even gets a real girlfriend later.
