Haru and Gaku are former classmates who meet after both have interviews at Dragon Bank, a major company in Japan. Haru is a great communicator, bluffing his way into and out of various situations, while Gaku is a computer geek and has zero soft skills. They develop a roadmap (read: a comic, absurdly-detached-from-reality wishlist) to gaining trillion dollars and conquering dragon bank.
The series makes absolutely no sense from multiple perspectives. Watching this you would think becoming a rich person is a board game. There is little reality behind the business decisions, and it's all moving super fast.
However, the series is also fun in an absurd way. It's extremely entertaining to watch the tide being pulled back and forth.
The series has little to no romantic interactions, but I have to give it to Meguro Ren and Imada Mio for their chemistry. The "chemistry" word is so overplayed that it barely means anything, but if anyone has it, these two do. When they stare at eachother you can cut the air between them with scissors. Their characters, however, keep the enemies/friends game, all for the sake of their businesses. I am honestly very happy that nothing ever happens between them- but they keep the playful and sometimes downright offensive manner to one another. Their scenes were super entertaining, and I wish I could have seen more.
