Long-Lost Pals Living Their Breast Life 1 [EPUB ebook] 

You’ve heard of meet cute, but reunite cute? Now that they’re both grown up, newly swole Shun visits his old friend Nana after an extended absence hoping to put a (figurative) stake in the heart of his one-time first love. But it looks like neither of these tiddy monsters is ready to let go! Join our hilariously awkward (maybe?) couple as they (hopefully!?) begin to bumble their way into an adorable relationship!
