Thanks for the new chapter!
That was actually pretty sweet. Moeko really is a really good friend, I actually think that if Ichikawa didn't get close with Yamada, he would eventually get close with Moeko instead, especially that Moeko has an affinity towards inkya people. But then again, it was actually Yamada who noticed Ichikawa the first (sports festival at start of 2nd year).
I doubt anything more than a friendship would have developed, though. Moeko has made it very clear she likes sleazy, outgoing pretty boy types, like Nanjou-senpai (pickup-pai). Kyo (Ichikawa) is the exact opposite of that, being a gloomy-looking but good-hearted introvert. Maybe eventually she'd realize she could fall in love with someone like that, especially since she gets along so well with them (thanks to her big bro), but there's been no evidence her 'type' has changed, and I suspect the next closest to her type after Nanjou (who has moved on to high school, never looked at her anyway, and was snubbed by her on New Year's Eve) is likely Adachi (someone who has kinda-sorta expressed interest in her, if only through the whole valentines/white day sequence, even if he was still hung up on Anna at the time).
The big problem there is we didn't get any sort of actual development between them since the end of the sports festival arc where Adachi finally gave up on Anna, but then shifted to obsessing over Kyo's big sis, Kana. In the anime, the aftermath of the sports festival had Moeko drape a towel (albeit soaked) over Adachi's head after he came out of the infirmary, dealing with his 'loss' to Kyo with respect to Anna, which felt like some sort of relationship 'flag' moment, before Kana showed up and drew his attention.
The manga has had no such moment yet between Adachi and Moeko. I hope it happens soon, because I thought that moment was kinda cute, and there's a few other subtle things throughout the manga that feel like they could, arguably, hit it off. Also some volume/tankobon cover/liner art pieces depicting the whole class in volumes 2 and 3 where Adachi and Moeko were close together and interacting that implied, to me, that Norio maybe wanted to have them connect more.
