Three different stories and two shorts about the first two stories.
The first story about Maki Shinji and Sayama was really sweet and nice. You tipical drama between a couple with an age gap.
The second story was okay, but annoying and slightly bothersome. It's a story about two childhood friends that stay together in elementary, middle school, and high school. Shuu has social anxiety from constantly being bullied. Jun'ya is a friend that always protected him from the bullies but ended up becoming one to Shuu. It got really annoying after Jun'ya kissed Shuu and started claiming that it was Shuu who kissed him and got angry when Shuu tried to pretend it never happened. I had to reread that part a few times to really get it. Jun'ya kissed Shuu, so why does he keep saying that Shuu kissed him? It's annoying.
The third story is about Manaka and Segawa. They are high school students. It's a typical drama story about one hiding his true nature and personality. Found it to be a tad bit annoying and boring.
