These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Shiro no Eden
Ensemble Darkhorse: Surprisingly, Shuuto has been getting popular with fans, especially after Chapter 8.
Squick: Let's just say quite a number of readers were horrified by The Reveal that Mashiro and Ai are half-siblings.
Stoic Woobie: Ai. He may come off as a jerk at times, but it's indicated that there must be a reason why Ai became the person he now is—not that he would admit it or ask for help. Luckily for Ai, Mashiro won't give up on him.
