I just finished reading Haru Matsu Bokura and am having some major Second Lead Syndrome. So basically what I want is a manga where the leads used to be best friends as kids (it doesn't matter whether one or both had feelings for each other, they just have to be really close), and then they are reunited after a few years, and unlike Haru Matsu Bokura, they don't have a love interest or anything of the sort. They fall in love with each other again/for the first time.

Thanks in advance.
