Life: Senjou no Bokura

Practical Akira Ito and child-like Yuki Nishi bump into each other while they each play their own version of "the floor is lava" on a white line on the side of the road. Soon enough, Akira falls in love with Yuki, and he can't help but be frustrated about only getting to interact with Yuki during this game, which is why he ends up kissing him...

A beautiful love story about two teenage boys becoming men as we get to watch them grow older with time. Watch out! You may need some tissues while you read this tear-jerker. Life might change, but love never does.
