Then, as many expected it was our Vice president.Read further to even more spoilers....
So it was the vice president and Miso that got kidnapped by a woman, mentally ill.The prez played along the kidnapper cause she was crazy as F&#k.The arachnophobia that miso has is due to that fact that both kids witnessed a suicide,so as the woman hung herself Yongjoon told miso that it was a spider.This incident is also the reason why he has nightmares and daymares? Anyhow the older brother was the one who left Joon behind,so after they found him,he (older bro) went to see the scene and got even more traumatized as he felt guilty.He sarted having attacks and then he suddenly changed his mamories.And started thinking it was HE who got kidnapped and blamed Vprez.Problems at home cause mom was worried sick about the bro's behavior so lil brother fainted suddenly and after that changed his own name and acted that he'd forgotten everything about the accident. (=・ω・=) everything I said was based on what I saw in the drama so forgive me if the manga differs
9 years old... Do you know when I was 8-9 year old and my sis was 6or 7 years old some people try to kidnapped us. I said a lie about my house because they tried to go to car baggage us my sis went with them but I hold her hand and I went to nearest house. I waited there .And then we went to our house immediately but I talk about it because I was so afraid of to talk my parents. I thought they will mad at me. One women who is saw us in the window came to our house and talked with my parents. And then I realized I was hero my sis. (⌒▽⌒) anyway... I dunno why I want to say this. But when I see this I remember this accident. Anddd do you recommend any web or manga to read. I have been reading manga nearly 3 years. I can't find manga now...

This could be easily resolved if Miso just spoke with VP's mother or father. She just has to guess they're the people who know more about the incident, even more than the two brothers
