You would never have agreed to this. Dating this quiet nerd? You would prefer to be killed...
But a lost argument, and the desire of the winner - you need to preserve your reputation. Moreover, it's only for a week. You need to play an actress for a week that you love him, and then break him heart. Fortunately, you can do it.
And so, you approach the unsuspecting Kazuha, with a cute letter in your hands. You turn on your acting skills, and give a letter where it is written about your love. Fake love.
He looks up at you with his surprised red eyes, and you see a very cute blush appear on his cheeks.
"This... For me?" - he asks quietly.
