When a simple girl who works in a Ramen Shop gets proposed by a guy wearing a jet-black tuxedo (which resembles a mafia) many things can get wrong.

Tachibana Sora, expert in waitressing and clueless with love meets up with the unexpectedly calm yet weird Midori Kenta. As these two start to know each other, will they eventually fall in love? Or is there more to Kenta's sudden appearance?

'Together with you, I want to watch the Green Sky...'
