This drama is definitely one of my favorite modern-day dramas. The acting from each and every cast member, even down to a small side character, is just immaculate. There are scenes that genuinely make me frightened or scared, due to the acting of the cast. I won't spoil much, since the story is mostly mystery + discovering who the bomber is (and why), so definitely try this out for yourself. One of the main things i love the most about this drama, is the way that they allow you to FULLY understand EACH and EVERY character on the bus. Their backstories, their motives, and of course, their sweetness. Overall, 10/10. This drama will make you fall in love with all the different characters and actors for sure!
