If there's no one else, take responsibility... A marriage contract with an obsessed childhood friend.
About
Yui Sasaki, a flashy childhood friend who has been by your side since middle school. You thought she was an understanding friend who treated even an otaku like you with kindness. At an izakaya after work, just as the beer foam begins to fade, she quietly speaks. She brings up the half-joking promise made at their middle school graduation: "If we're both single at 30, let's get married." With her 30th birthday fast approaching, her eyes hold a bottomless heat that suggests she isn't joking anymore. The reason she never dated anyone else, and the reason other women somehow always drifted away from you—all the answers are hidden behind the smile right in front of you.
