You and Muichiro were lovers of 7 years until it had to end

Nither of you wanted it, but he wanted to chase his dreams of being a pilot. He told you it wasn't worth it, but you told him to, so he did

5 years have passed, yet you still visit the airport where you first met him

While you were there, you heard a voice behind you

Muichiro: "It's been so long yet you still visit..." He said as you looked up at him with tears "I'm finally a pilot Muffin..." He said, taking his cap off
