Tokyo in April is...

As kids, Kazuma Takizawa and Ren Ishihara were the best of friends. Nearly inseparable, the two did everything together. But when they reached their third year of middle school, everything changed. Forced to move to America, Kazuma left with almost no warning, bringing his friendship with Ren to a very abrupt and unexpected end.

Ten years later, Kazuma is back in Japan and excited to begin his new job. Completely unaware that Ren is now working as the company's top designer, Kazuma is shocked to see his old friend again. Thrilled to be reunited with Ren, Kazuma hopes they'll be able to pick up where they left off, but Ren seems to want nothing to do with him. Keeping Kazuma at a friendly distance, Ren acts more like a former classmate than a former best friend.

Struggling to understand why Ren is being so cold, Kazuma decides being around Ren at work is enough. Content to have him back in his life, Ren tells himself he's happy, though deep down, he hopes to have his old friend back soon. With time, will he be able to win back the affection of his best friend and first love?
