In high school, I was dared to play "gay chicken", which is where two straight gals pretend to be gay and the first one to chicken out loses...
The other gal and I are really stubborn, and neither of us wanted to lose. We've been married 14 years and run a Ryokan in Kyoto with our adopted daughter. If that gal doesn't chicken out soon, I'm going to start to suspect she is actually gay.
I get the feeling that the name "Mareshino Rui" is a deliberate play on the word maraschino (especially considering I've never heard of that being a Japanese name). As in the Italian maraschino cherries. Seems to imply her sweetness & perfection is "artificial" or "manufactured." Just a fun little detail they decided to include that I thought would be interesting to point out. I love when authors add I suppose "easter eggs" in a way like this.
