Hadigirl (Manga 2.5)

Sae is a high school girl who is too shy to even talk to guys. One day she gets visited by a fairy who gives her various "love challenges" like "holding hands," getting an "indirect kiss" or giving a "lap pillow", promising true love as a reward if she accomplishes every task. Now join Sae as she struggles to complete these challenges.
