This was such a damn cute show!
I really loved watching Maruya-kun's asides/monologues they were so cute and hilarious.
I thought Sanada-san was so deadpan and funny, but above all I loved the harmony between all the characters.
I would've liked to see more development with the "mysterious old guy" and also Maruya-kun's family and some other additional characters. It definitely felt like there were slightly too many underdeveloped characters for the length of the show.

Overall, as the title promises, a cute drama that you can crack open a beer and enjoy! Cheers!
