ReRe Hello is a good story. But I really expected more from it. It's that type of shoujo where u have to wait 20 chapters for confession and it was really annoying. The plot is so promising, but there's no drama and not much comedy either. MCs are ordinary, without special characteristics. Story is sweet and cute on it's own way, but I was too annoyed that I had to wait so long that I can't even feel it's cuteness.
Art is good.
So, for me this manga was boring to read. I couldn't get attached to characters.
If you're ok with so stretched plot, with classic shoujo elements than you might like it.
