Kashikomarimashita, Destiny
Complete | Sachimo | 2015 released
Multiple pairings. I like the second pairing which tackles the very realistic instances of wanting to be with someone who's not your "fated" yet overcoming all such obstacles to MAKE A CHOICE to stay with the one you love rather than the one you're biologically attracted to
Shounen No Kyoukai

Multipairings. About people choosing their partners based on their love for them, and not some hormonal drive
