This was called Behind that Wall before. ( just so saying, if you're wondering why you're reading a different story)

TEASERS:

"I don't believe it! I think I'm falling for her... It's because of this CRAZY LITTLE THING CALLED LOVE!" He slammed his clenched hands to the wall. His hand swollen, he touched his chest where his heart hammered so.

"Open your heart, darling. Love, it's such a crazy thing but I don't know... You made me become what I really was." He said caressing her cheeks with the back of his hand. 

He thought, "Love made me crazy enough to fall head-over-hills for you." He brushed away the tears from her eyes and cheeks. He gave her a light peck on her right cheek, making her blush.  

"I love you, and that's what really matters," he said in her hair, as her hands braced around his waist. Tears streamed down, as she buried her face in his chest.

"Saranghae. You are the best thing that ever happened to me!" She whimpered against his chest. Tears were stinging her eyes.

"I never really thought I will fall in love with a person like him," she said in a muffled voice as she covered her face in her pillow. Her heart beating so fast in her chest just by thinking about his face.

"I will never leave you. You are the only one in my heart and will always will be... Forever," he said and took her into his arms.

He cupped her face in his and leaned in. Their lips touched, and it created sparks. Their hearts beating rhythmically against each other. She curled her fingers around his hair. He deepened the kiss and she gasped. "Saranghae," he murmured against her lips.

"I told my myself I won't fall in love again... But you taught me how to love again," he said as his arms braced around her waist. "There will always be this crazy little thing called love," she said and gave him a smile that showed how much she loved him.
