I rewatched this drama today, and it was as exciting and fun as it was the first time I watched it. Although, I do understand the criticism this drama got when it first got released and I still understand the perspective of their opinion and personal understanding, this kind of genre/ story might not be everyone's cup of tea. But ME? I eat it up lol. I will highly recommend this drama to people who like age-gap, brother's best-friend, and no third person drama, just like me. Both male and female main characters are two of the biggest green flag I've seen in my drama history(i.e 7yrs btw). Visuals are great, the OST is a bop, pacing is great too. I very rarely give 10 on 10 in any of my watch. The last 10 i gave to a drama was 'The Untamed'. So this is definitely the best(10 on 10). Give it a try guys.
