I can see how other reviewers are getting a Rick and Morty vibe in the delivery of the boyfriend, but to say that a specific cadence is intellectually owned by a popular show is bonkers. As if that's where it came from. (Meanwhile you could argue R&M is a knockoff of various other properties)
Otherwise, solid cartoon! The background usage was a bit iffy and some parts probably could have been boarded a little more coherently (particularly the bits of dialogue). You could've probably also shortened/cut out altogether one of the boyfriend's ramblings. The animation was great and the writing was pretty sharp. The ending absolutely caught me off guard.
Nice job!
