Sekine-kun no Koi

Keiichiro Sekine, age 30, is an exceptionally "unfortunate" man. Though he's a hot, elite businessman who's popular with both women and men alike, he's cursed with a "triple handicap" of being insensitive, passive and a jack-of-all-trades, but master of none. Having lived a life that's been somewhat out-of-focus, Sekine resolves to make a change and heads for a small knitting and handicrafts store. While knitting and counting the stitches, Sekine finds himself recalling horrible memories in his past and the feel of his previous upperclassman, Kazune's, bone-thin body! But after meeting the store owner's granddaughter, Sara, Sekine's love life might finally begin... or not. (Source: JManga)
