Junjou U-19 is the 3rd single by NMB48. Debuting at number 1 with 329 thousand copies sold. It's a fun song, it should have been top 20 but I guess this will do.
Kitagawa Kenji is the 6th single by NMB, debuting at number 1 with 317k copies sold. Suilen states that it's pretty weak for their standards. I mean I can kinda see where you're coming from but they still have worse left in.
