I've been keeping up with this series (since you told me to read it)
overall great story, but pacing is a bit slow sometimes. Depth of characters is amazing, but I would've liked to see more Yuna in the earlier chapters. Dialogue and characters are realistic as hell, they actually feel like just real people recounting a journey, or a second-hand retelling of the events.
Takumi went from "god I hate this guy" to "damn, he changed"
This is an amazing depiction of being a victim of circumstance, Takumi's misinterpretation of worth, Yuna being painfully honest. Both are victims of their own, individual circumstances and this story shows that you can stand up to this with the help of other people. A small detail I liked is that Takumi and Yuna's relationship never seems dependent on each other, they lend a hand and support when they need.
I enjoyed reading this, and I can't wait to see what's next for you as an author and the universe inside of Iris.
