Great third page, Koio! I really like how you are making use of the expressions and the angles. That's kind of interesting, Koi's heart is thumping, I guess? I'm not sure, I can't read the japanese. I thought it was kind of interesting for some reason, maybe she was surprised by running into Rei, but I'd like to see how things turn out. Great job so far.
Speaking of rain, it's been raining quite a bit over here where I'm living, so it kind of puts the world into the mood of your comic. That's kinda neat.
