When the Heaven's Smile

Takagi, rather a cute and innocent guy, is best friends and class mates with Kumoi, the tall, intellectual guy. One day, Takagi sees a pencil sketch of a person in between Kumois notebook pages, stunned to find a sketch of a man, resembles his older brother. So he asks, Is that a picture of my brother…he passed away 6 years ago…? Kumoi responds, no, no… thats nobody. Its just a doodle of a random guy. Takagi tells himself that Kumoi couldnt have possibly known his brother and that this was just a silly fluke and the drawing was nothing but a random drawing… but he cant stop thinking there is something more to the sketch…
