Hiromu has a cute smile.
Two episodes only, and I'm so in love with this series already. I like all three kids so far. I'm paying some particular attention to Yoko because there is some "kodomo" concept involved there. If dealt with wrongly, a character can quickly enter the list of not-so-favorites, and that's the last thing I want for her because I like Yoko so much so far. She has great potential as a character and I really want to see this fly.
With that said, I might be inclining towards Ryuji.
On the pairing side, it's almost certain at this point that I will ship Hiromu/Yoko, after all. And to think, when the casting rumor brought up their faces for the first time, based on info alone I had liked the idea of Red/Yellow. Of course, I had set it aside because there was absolutely nothing to go with back then, and I do have some tendency to incline towards Blue/Yellow (even if in the end I don't necessarily ship it, and in this case I didn't really think I would).
...So I guess first thoughts do stick with you. (huh?)
