Hitomebore shita Toshishita Danshi to xx suru Koto ni Narimashite

Head over heels for the first time in 10 years!! 29 years old and with no one to call a significant other, Haruka's been focused on her work to keep her mind off the turmoil of her (nonexistent) romantic life. That all changed though when she bumped into Chikage, a student at the nearby university... love at first sight! This is all so new... or rather it feels like it since it's been too long... but now Haruka's got to figure out how to close the distance and learn more about this person she just happened to be looking at from afar for so long. One day, on her way back from work, Haruka decides to browse the bookstore near her office when, lo and behold, Chikage's working the register! Who would've thought it'd be Chikage that pops the question?! "Will you be a practice girlfriend for me?" ...Practice?! (Source: MangaPlaza)
