Kimi to Aoi Haru no Hajimari

Suehiro is a quiet girl, who prefers the excitement of her books to the real-life anxieties of friends. She'd been perfectly happy in her own little world until ultra-popular guy Takasago asked her out as part of a punishment game right in front of the class, bringing Suehiro front and center. Mortified, she tries everything to get away...but he persists, and insists he's serious! How will she deal with such an interruption to her previously quiet life?
