Both deal with university students navigating their first gay relationship, neither have a major focus on actual school and moreso the extra-curriculars and relationships. They both take a more mature tone, though Together With Me is a little more mature based solely on how far the scenes actually go (*wiggling eyebrows*). They both have that sort of aggressive, "I love you but screw you" kind of dynamic.

I started watching more of these kind of reality shows about love and dating because of heart signal! Romance Package is new, just one episode aired and I'm already loving it! So if you like heart signal, I'm sure you're gonna enjoy this one too.
