Very good art, nice story, but it would be great if there were a few more chapters in the middle part. At the beginning they are in high school and then suddenly at work/postgrad students. I prefer the way they look when they are older (the story in the second part is also better). I would definitely read a sequel with Sieta (if there was any).
From the 6 chapters that i've read i don't feel satisfied it jumps half way through: no explanation of what happens in the middle, includes a random love triangle just thrown in and doesn't have a sound ending so far on a positive note i like the way they look when grown up rather than when they were younger I dont know what else to say about this i think it needs some additional material ....
