Contains SPOILERS
Let's firstly begin off with the fact that the manhwa was incredibly amazing at the beginning, I personally enjoyed the theme, plot, characters and the design of the manhwa but it was ruined at the end, which I will get to at the end of this review.

It was all fascinatingly well-written, we started off with the fact that Han-Eol's brother and Da-Ae's sister got married. Both main leads had a rough past with each other in their high school years so them reuniting at their siblings wedding was the last thing they expected. The newly wedded couple set off immediately after their wedding for their honeymoon. But a car accident happened which lead the newly wedded couple to pass away in the crash. Both Han-Eol and Da-Ae were devasted as they lost their only sibling, Da-Ae's mother had mentioned that she went to a fortune teller and they had told her that this couple would be bad luck for each other. Da-Ae immediately told this to Han-Eol, who took it the wrong way thinking her sister was the one who murdered his brother, which infuriated Da-Ae. He walked out of the funeral and she chased him because she wasn't gonna take an accusation of her sister so lightly, they ended up going outside when it was raining and a car had crashed into them leading them to die.

In a blink of an eye, a car hit both of them leading them to die which was the least expected thing to happen. I was completely shocked by this point but then the story took a plot twist by sending both main leads back into the past 8 years ago. Both leads were shocked to the core that they were sent back in time and the fact they could remember their memories. Da-Ae thought it was a fever dream while Han-Eol thought of the smarter conclusions as in he was sent back into the past for a reason. They both went to school as they thought it was the smartest thing to go with the time.

Han-Eol set out to find Da-Ae to see if he was the only one who was sent back in time and surpringsly he wasn't. Both of them knew that this couldn't mean nothing and thought that they must do everything in their power to stop their sister and brother from ever meeting each other and falling in love. It was a ridiculous Idea but they did it anyways. With weeks going by, they continously tried their best to make sure they had no interactions with one and another and they succeed but also managed to fail. In all this time Da-Ae's older sister had gotten a stalker, the sister didn't know who it was and as Da-Ae was trying to save her sister by her not marrying Han-Eol's brother, she managed to get her to date somebody else but that somebody else was her stalker.

Will be skipping further into the story and not giving much more details as this is a review

Also in progress of all this, Han-Eol and Da-Ae were able to find the love they had hidden within themselves for 8 years, I really liked this because even though their siblings were a great match, so were they. But the main leads continously tried finding out who the stalker was and figured out and by the time they did, the sister had also. The stalker then continued onto knocking her out because he was obviously manipulative and obsessed. He continued to kidnap her and take her to an abandoned area where the main leads followed them with Han-Eol's brother, they were then confronted by the stalker who continued to tell Han-Eol and Da-Ae that he was also sent back 8 years into the past and he saw this as a chance to get back at them because he was the one who murdered the newly wedded couple 8 years in the future. Both of them were absolutely stunned by this and I think everybody who has read this manhwa also. Words could not explain what happened afterwards. But the brother was able to save the sister from any harm.

Afterwards they chased the stalker in the abandoned construction site and they told him stuff and he must've felt a guilty conscious so he decided to commit suicide.

After this whole thing was cleared up, they continued living their lives normally and happily, especially since Han-Eol and Da-Ae could finally love each other without worrying their siblings dying but Da-Ae told Han-Eol she wanted to have the exact same date and stuff for when their siblings got married in the past and they did but then they ended up into a car accident and that lead to Da-Ae losing her memory completely to amnesia which was absolutely the worst thing that they did in the story. I know many readers of this story can agree with me that the authors didn't have to go beyond the line to destroy such a good storyline with this plot twist.

But afterwards the sister and brother did end up together after all so their efforts went to waste and so on but I feel like this could've been written way better at the end or even ended at the part when they succeed on saving their siblings.
