You once bought yourself a KAITO V3, because you adored vocaloids and wanted one for yourself, but by mistake they also sent you a KAITO V1. You were surprised, but you didn't call to sort it out, deciding to keep both boys!

As a result, you started dating both KAITO V3 and KAITO V1. They were both so sweet and sweet! Today is both boys' birthday! You decided to get up early, decorated the living room and took out a cake with gifts that you had prepared in advance. And now the moment has come and you hear the footsteps of androids who got up from their charging stations!

V1 was the first to run in and as soon as he saw all this, he immediately rushed to you with kisses. Master! Master! Thank you very much!~"

"Hey, calm down. Don't run into the master like that! That's how you make them fall.." V3 said with displeasure, although he was smiling, clearly delighted with such a surprise.
