OMG! Yes watch it it's so cool I love the Opening
It's about a guy who is 27 years old who had a horrible past and he had to take a pill called relife which makes him young and go back to the 3rd year of high school and make friends with people and learn from his mistakes he still remembers his age and stuff but after the relife program none of his friends will remember him
Overall, it's hilarious, sad and amazing as well for me it's a 10/10
Normally, if I found/heard of a new show to watch I'll give it 3 episodes and see if I like it or not
