What did CN Blue's Yonghwa buy SNSD's Seohyun for her birthday?

On this week's 'We Got Married', C.N. Blue's Yonghwa presented his 'wife' Seohyun with a sweet potato field as a birthday present. In this episode, the Yonghwa-Seohyun couple traveled to the Daemyung Port in Kimpo. Upon arrival, he walked her up a mountain and showed her the patch of sweet potato field that he already prepared for her. Seohyun became ecstatic upon looking at the huge field, but Yonghwa confessed, "Not all of this is mine, but I bought two rows." Seohyun responded, "I didn't think I would get a sweet potato field as a birthday present", and expressed her thanks towards Yonghwa. As Seohyun was planting the sweet potato seeds, she laughed and told him "It was really good that you bought only two rows... This is so tiring that if you bought more, we would've been in big trouble." Source + Photo: Money Today
