If I Take Your Hand (2010)

Blurb
To make a choice is to take a risk, so Hinata simply coasts. When the older Kasahara pursues him, Hinata allows himself to fall into an awkward friendship. But Kasahara demands more and Hinata’s hand is forced: will he take a risk and face his fears, or will he stay in his comfortable but empty life?

Kozuki used to risk falling in love, but too much heartache has crushed his belief in “happily ever after,” so he rejects his co-worker Sakashita’s confession. However, Sakashita’s love just won’t fade. Will Kozuki take one more risk for love before it’s too late?
