Watashi no Suki wa Kakusenai

In the spring of her first year of high school, Rin Misaki falls in love with the manager of the restaurant "Asahi", after he treats her kindly at a neighborhood festival. She hides her love for him and gets hired as a part-timer, and tries her best every day to be useful to the manager. As they spend time together, Rin's "love" only grows, until it's on the verge of overflowing! So please, don't make me so happy~~!
