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.
Kanade: Arou-kun, you actually have a yukata, too?
Arou: ... I borrowed it from Namiki.
Namiki: And I was the one who dressed him!
Arou with Honma, his classmate from junior high:
Honma: I was sooo happy at that moment! It was kinda like being with an unfriendly cat that you suddenly manage to win over! I wanted to give him a hug right then and there!
Kanade: You must have... really liked him!
Honma: Arou is... special.
Jerkass Woobie: Sou is a character you want to punch a little but sympathize with at the same time. At one hand, he puts Arou in so much trauma trouble by leading him towards an overdose of memories of Sanae, including her death, and even tries to endanger Arou (by pushing him into moving traffic) in order to get into the same situation as Arou did when Sanae died so he'd be able to unlock the unlimited extent of power to see the past that Arou has. But on the other hand, you can sympathize with Sou because he just wants to see his only sister Sanae again.
