Boku no Okusan wa Chotto Kowai

With how far she's out of his league, Kosuke Shimizu never expected his senpai at work, Natsuna Shirahama, to go on a date with him...much less marry him! But with a wife so perfect, it's no surprise that the timid and indecisive Kosuke feels inadequate...and not just in bed. The truth is, they both have their fair share of flaws (especially when it comes to expressing their love), but working through them together will only strengthen their marriage...right?
