Touch, the TV series, is based on the manga (Japanese comics) by Adachi Mitsuru. It was shown on television in 1985 (yes, it's that old) and ran for 108 episodes. In 1986 and '87, three movies were released, summarizing the series. In 1998 (yes, that's right), there was another Touch TV movie made, named Miss Lonely Yesterday, which takes place five years later. The movie you're watching today is the first movie, which summarizes the first part of the 108 episodes -- the love triangle between the three main characters.
Tatsuya and Kazuya Uesugi are twins brothers. Kazuya is the intelligent, diligent, and athletic twin. Tatsuya is the lazier one who doesn't take school work seriously. Minami Asakura is their childhood buddy and neighbor. They were all born in the same year and always played together as children. The problem was, they ended up breaking everything in sight, so their parents built them a room of their own in the yard. This room became a study room when they were more grown-up.
They are in high school, and Kazuya is the star pitcher for the school baseball team. Everyone's proud of this mature and capable teenager. The few episodes I've seen of the TV series show that Tatsuya is also an intelligent and athletic boy, when he wants to be, that is. He can achieve so much more than his brother when he works at it, but he doesn't want to make his twin brother feel inferior, which is why he acts the way he does.
So this movie is about love and baseball, but you're going to have to watch it to see who really likes who. (What, you thought I would spoil it for you? You must be kidding.) Even though Touch is kind of old, it gives you this warm and yummy feeling when you watch it. Oh yeah, there's this incredibly adorable dog named Punch.
