Definitely not "the best BL series ever" but it was very enjoyable and better than most. I think the plot kind of got messy and boring somewhere around the last two episodes, but I liked the happy ending and the previous episodes were so good that it didn't affect how I felt about the overall story that much. I would have liked more intimate and personal moments between Tol and Tin if there was more time rather than focusing so much on side characters, but the moments they did have secured their chemistry and made for a really cute romance. I really liked them as a couple and I've never seen the time loop trope done this well for a BL before so I'm happy about that. Some people didn't like the focus on Tol by episode 11 but I found it to be necessary and satisfying, I just think it could have been executed better is all. I think my favorite part is that it's only after you've gone on this journey with Tin that you realize he wasn't just saving Tol, he was saving himself. They are both selfish characters that were only able to become better people together and I found that fascinating.
