Kagamine Rin had a lovely and romantic boyfriend, Len. Every day, after school, Len would always walk her home with his arm around her neck. Sometimes, he would share with her a two headed straw in a drink and other times he would treat her to an ice cream Sunday.

One sunny day, Len wanted to spend sometimes with his girlfriend and decided to book a couple of tickets for a trip to the most famous romantic city in the world, Paris the city of love. Rin was happy and nervous at the same time as Len told her. She was worried what Len might do to her, but as long as they sleep in a different room, than everything will be fine.

Before the flight, Len noticed Rin was scared because that was the first time she had a boyfriend with her on a trip. Len kissed her on the cheek and looked her in the eye and said," Sorry if this is your first time, I'll protect you with my life" with a smile from Len. Suddenly, Rin doesn't feel afraid anymore and she nodded and laughed at herself. It was a long flight and a lovely night with a very little light. Rin and Len was sleepy but they could not sleep. They just have to wait until one of them sleeps. Just then, Rin accidentally slept and felt over to Len's shoulder. Len had smelled a scent of sweet orange from Rin's hair. 'Rin just love too many oranges,' Len taught to himself. He took Rin hand and kissed her and said, "Good night my lovely princess." Len spend every moment with her even though she was a sleep but finally he slept and his head fell onto her hair.

The next morning in the airplane, Rin was the first one to wake up and found out that she was actually sleeping on Len's should! Rin was screaming in her mind and quickly moved away from Len. Then Len also suddenly woke up and said, "Good morning! You look like an angel when you were sleeping last night." Rin blushed and her heart beats fast and said, "I'll go brush my teeth first!" After Rin comes back from back from brushing her teeth, Len bought delicious food for her. He bought her some muffin, cake with oranges on the top, tiramisu and her cup of hot cocoa. She had a big smile in her face and wonder why her life his so perfect and how can she meet such a lovey boy that she also coincidently loved so much.

After they had done eating, Rin was so happy and said with a smile on her face, "Thank you for buying me all that delicious food, Len!" Then Rin was going to say something out but she couldn't then Len saw her with her weird expression then he asked her, "What are you thinking about?" "Oh, nothing!" replied Rin. Then when they arrived at Paris, Len stand up first and Rin was going to tell him but couldn't. Then Rin asked him to wait then suddenly, Rin couldn't take it anymoure and said it out, " I LOVE YOU, LEN! Thank you so much for loving me." When everybody went out of the plane, Len quickly hugged Rin from the back and said, "I love you too, my princess." Rin blushed so red like blood and turned around to hug him back. "I will stay by your side no matter what," Len told Rin claimly and it made Rin really happy to meet a guy like him.
