Because other foster children came to their house before her father's death. Ji uk came to her house after her father died, which means that despite knowing that Hae Young left house after her husband's death due to a foster child's father, the mother brought another foster child to their house. In addition, Ji Uk hid his identity. She's also probably kinda jealous/regretful that Ji Uk lived with her mother before she started losing her memories, especially after going through her mom's diary which mention Ji Uk.

Don't think there will be a breakup because the preview seems to want to make us think that they will break up. There's no way the ML or FL let each other leave.

I saw comments on YouTube that both dads know about the leads' relationship. Was there any sign?

I don't get how the actress who played the youngest daughter isn't cast as a lead actress in other dramas. She's so good in this.

I could because the Bok Gyu guy is a great actor. He has played both funny and villain characters, so I knew he could turn this around.

why?

Because the CEO wrote hate comments that were bad enough for the 2nd FL to pursue a case against him.

The FL was introduced as a mean girl, yet all I see is a woman with a good heart. Her only fault was to hide her past from his ex's wife, which can be justified to some extent since that wife is a HR lady.

Writing has been great for the most part, except the ML's decision to hide his background from the FL. He expects the FL to treat him better and acts like an angelic guy, yet he completely hides such a key detail about his background, especially when the FL has trauma related to her parents. Jerk move to be honest. The FL is rightfully pissed.

The eldest sister in this has one of the greatest characters (both male and female) in k-drama. She's so cool from beginning to the end.

The FL's character and acting is too good. Even the SFL is very watchable. One of the strongest pairs of female leads in a k-drama.

Is the SML's wife alive? Maybe paralyzed or something? Because the SML seems to hide something. He likes SFL but something is stopping him.

Can't blame the Son Ye Jin links. Their chemistry was the best I have ever seen in a k-drama.

So, in the end, Sunwoo and his brother stay alive in the final timeline?

In episode 15, does the nurse say, FL went through that memory experiment?

This was such a good drama. But, the ending was depressing.

Because the experiment he did on the rat made it die. He hid the results. Now, he's trying to do the same experiment on ML.

Why does she like the secretary? Because he was handsome and did one kind act during school. We all have these kind of crushes. So, it's easy to see that she might like the boss after knowing him better, especially when their likes are similar.

Same

The brother doesn't know that FL is his brother's first love.
