The story of the lil bro trying to chase the older sister ((not blood related)
Seriously someone should update the summary of this drama,..
Female lead studies psychology and contemplates whether to do grad school. Male lead is 6 years younger than the female lead. The female lead was always there to take care of him. He has always had a crush on his “sister”. He;s obviously a little more naughty and playful , while the. female lead is more calm and collected. The dad always tries to set her up with dates. In order to stop the dad from setting more dates the male lead claims the female lead is pregnant! lol starting their fake romance!
Although their relationship is super cute! like you could totally feel the love of the male lead for his sister….. They kinda have a weird relationship. Weird in the sense… is like i thought they were together, wait they actually arent,,,, they have miscommunication, break up, get back together. They get their marriage license… yet the male lead still proposes to her. It just seems like a back and forth chasing…Like the female lead likes him but i dont even know when they were offically together.
The story development is a little lacking in the sense that it just goes back and forth between the leads. I didnt feel much character development from the female lead or male lead. Also they made it mysterious as to why the male lead eats candy /sweet he gets an allergic reaction They dont really explain or elaborate on it.
