Touch it and it gets hard!

Haein and Dohyun have been childhood friends for 20 years— so close, they pride themselves on knowing each other better than anyone. While studying sports rehabilitation, Haein volunteers to help Dohyun, a baseball team member, with muscle therapy for her practicum. “What could possibly happen?” she thinks—naively. But the moment her gentle hands touch him… Dohyun’s "reaction" gives a very different answer. Can two decades of friendship survive the tingling spark of desire? A sweet, sticky romance about discovering the true feelings hidden just beneath the surface!
