What if you were to meet your childhood friend again after ten years of separation? This was exactly the case for Mitsuya, a recently transferred company executive who found out that the person living three doors down from his new apartment was none other than Noboru, his older brothers best friend... and his first love. As a young and brash middle schooler, Mitsuya had forcefully kissed Noboru and drove him away. Deeply regretting his action, he kept a tight lid on his feelings. But now, being with Noboru again is bringing all those heated memories back, as if they were never gone to begin with. "Merry Checker" is adapted from this manga.
