1. Ryuu and Uta - Theyre the most interesting in that they’re already a couple but their past is what threatens to destroy what they’ve built in the present. I feel like Ryuu should tell her what it was like and apologize for acting like a tsundere, but I understand where he is coming from. I am dreading the inevitable drama but in a good way. It’s necessary for them to become a true couple.
2. Maria and Jou - Their extra chapter really shot them up for me. Jou really needs to get with the times here, it’s what’s really keeping him from truly making Maria happy. This is the 21st century, not the 18th. You’re equals now.
3. Yahiro and Hina - The reincarnation really adds more depth to this, especially in the chapter where the present Hina gets sick. It might just be a precocious crush from the outside, but knowing their past lives can really make you understand where Yahiro is coming from. The age gap may put people off, but I don’t mind personally. Plus, it makes for a real cute dynamic.
4. Hikari and Suzu - Their extra chapter was really good. They’re a nice pair, and Suzu’s real fun, though I don’t think they have as many elements to their relationship and interactions when compared to the other three. I’m just more or less waiting for present day Hikari to slowly remember his past with Suzu. Maybe then, Suzu will become more mature about her feelings.
