guys i need some spoilers
"I'm currently on Volume 13, so I still have a long way to go... In my opinion, given how the story is progressing, a harem ending seems clearly visible, unless the author decides to give us the middle finger. But honestly, the girl I'm really drawn to and love in this series is Christina. However, unlike the other girls, I feel there's very little development in their relationship so far. I usually avoid spoilers, but I really want to know if their relationship actually grows or not. Does Christina fall in love with him, and what are Rio's feelings? I saw somewhere that this girl's arc seemingly starts around Volume 27. So, my question is: what is the current status of their relationship, and do you think she will get as close to him as the other girls—like his sister, Aishia, Celia, and the rest—and could end up with Rio in the end? Honestly, knowing this might even affect my reading pace."
