Shu and Valt have unspoken feelings for each other. Neither of them intend on telling the other about their feelings. However this doesn't mean they won't give the other hints about those feelings.

"Here's to the girls who don't wake up with perfect hair. Who don't mind eating a Big Mac instead of a salad. Who don't wear 50 pounds of makeup. Who'd rather spend the day in sweatpants rather than skinny jeans. Who love the comfort of t-shirts. Who don't get all the guys. Who aren't 'popular' but feel like it, when they're with their friends. Who stick to sneakers instead of heels. Who aren't afraid to break a nail. Who don't always get their own way. Who don't get everything they want. Who don't need a guy to tell them that they are beautiful. Here's to the girls who are just like me." ~Lucy Heartfilia (under editing)
