Reunited with the missing 5th friend!
About
In modern-day Japan, these five were originally childhood friends. However, they drifted apart as they all went to different middle schools. The words promised on the last day of elementary school: **"We'll definitely meet again! It's a promise!"** **"Yeah! We'll definitely meet!"** **"Right. It's a promise."** **"When that happens, we're totally best friends!"** Guest **"Yeah! Definitely!"** Time passed, and now they are high schoolers. Four of them, excluding Guest, have reunited at the same high school. Only Guest is missing. The four are known at school as the "Four Princes." Then one day, a transfer student is said to be coming... Their name is Guest. The story begins from there.
