I'm Married to the Girl Next Door?! Straight Up Edition

I'm Married to the Girl Next Door?! Straight Up Edition is a streamlined version of the Japanese erotic visual novel Oku-sama wa Onee-chan!? which removes those pesky choices that are often found in visual novels to provide a completely linear experience, turning the game into a kinetic novel. Events which were previously exclusive choices now happen directly after each other, meaning that all content in the game can now be experienced in one playthrough.

Like in the original game, the player assumes the role of Toshiya Sakagami, a young student who has a crush on the girl next door, Yukari, who is like a big sister to him. Toshiya is saddened to hear that Yukari is getting married, but his feelings about the marriage change when he discovers that he is the one that Yukari is getting married to! Apparently, their respective parents arranged the marriage years ago, but Toshiya is only just now finding out about it. The game follows Toshiya as he settles into his newly married life with Yukari while also bedding some other girls along the way.
