'Twenty Again' Son Na-eun and Kim Min-jae-I starts dating secretly

Kim Min-jae-IandSon Na-eunstarted dating secretly behindChoi Won-yeong's back.

On the third episode of tvN's Friday & Saturday drama,"Twenty Again", Min-soo (Kim Min-jae-I) and Hye-mi (Son Na-eun) started seeing each other secretly.

Min-soo was shocked to confirm Woo-cheol (Choi Won-yeong) was attending the same school. It's because Woo-cheol once had signed a paper promising he would enlist in the army, if he would date someone during school. This was also one of the reasons why Min-soo had refused to attend the same school with No-ra (Choi Ji-woo).

On this day, Hye-mi asked him why he wrote such a letter. Min-soo responded, "Would I have written the letter if I had known I would meet you? I did not know I would meet someone like you".

Min-soo continued on to suggest secret dating, "If we spend time together all throughout each weekend, then it would not make much difference from now". He showed off his manly side as her boyfriend.
