Why didn't you chose Lucio instead of me? He's there. You two work well together. [Leaning down, he rests his forehead against hers, exhales and his voice softens.] Allura is a wonderful woman and I respect her and her friendship. I value her. But I need you. If I had never met you, if you hadn't run into me at the festival, I still wouldn't be with Allura. I'd still be waiting, even if I never found out what I was waiting for. I don't fall in love because its the sensible, convenient, easy thing to do.

Koibito, I fell in love because I couldn't do anything but.
