The OST is absolutely stunning, and captures the meaning of the series so well. The scenery and settings are all beautiful, and I love both the plot and script. The cinematography is high quality, which is very visible in the crisp and accurate shots. The acting is very good, and I like that it’s not all about the couple, but about the characters they meet on the way as well. Everyone got a character development, and made each other stronger for it.

The explicit scenes were very unexpected from a Japanese BL, and were well executed. The only downside is that it totally ruined the mood at the end. It was great for the start of the series, but they should've made it less graphic to preserve the special atmosphere that they had going on in the final episode.

Now, let’s talk about the ending… I don’t know what to say, except that it was super frustrating and unsatisfactory. Although I believe this was the best way to end the series, it still felt incomplete. The reason for this is most likely because there were a number of things that were left unsolved, not including the meteor situation. An example of this is Yuma's "powers". This phenomenon should have been explained before we reached the end of the series.
Nevertheless, it was so worth my time, and I will definitely rewatch it in the future.
