All Because of You

The original author of *Zenbu Kimi no Sei* creates a completely original after story. You can read it without any worries even if you don't know the original work. It is a loving romantic comedy between two university students. (Source: Toranoana, Translated)

There's a “transsexual syndrome” where one's heart fluttering causes one's gender to switch. Sagimiya Ryou and Mikami Nagisa, both possessing this condition, find themselves drawn to each other and become lovers. Several years later, Ryou, now a university student, and Nagisa, who has become a teacher, begin their long-awaited life living together, spending their days all lovey-dovey.

One day, high school girl Kamishiro Tsumugi suddenly becomes a boy...?! A new everyday life begins with her female childhood friend and the boys in her class. This is a different story, set in the same world as *Zenbu Kimi no Sei*.
