As many might not have seen the film, for the questions & answers I will hide it.

L1 - Why is Shiqing the Chosen One to be the first to enter the Loop?
L2 - Why does Heyun's nose bleed? His health deteroriates after each Loop. What is the reason behind it? How come after the Loop is broken, he miraculously recovered?

Non-Loop Questions, "Plotholes" (N)

N1 - Why didnt Heyun break the glass early. It is a matter of life and death. Breaking the glass can allow easier transport of the bomb out earlier?
N2 - Why dont Shiqing immediately show the picture evidence to the driver. Instead of waiting for the driver to grab the bomb then reveal to him?
N3 - Why does the passengers reacted differently in the last cycle? The previous cycles they were all very passive to the scuffle?
N4 - The dropoff scene is abnormal. The driver should never stop in the middle lane, he could have let Meng Meng off on side lane. In the novel, the driver let her off. Afterwhich she was hit by a mixer truck when she cross the road which is more logical
N5 - How can the Bus company interviewer forget Wang Xingde? He was at the sign-off of the reconciliation letter. Worse part is why they even let him drive Bus 45?
N6 - How can the Chemical Company employ Cooker Aunt? She was diagnosed with mental and aggression issues after being asked to leave the seconadry school.
N7- Cooker Aunt insisted that Meng Meng is being sexually harassed on the bus (Which turns out to be true). However, when Shiqing accused Heyun, she did not
react violently eventhough she had prepared a knife. Since she already planned to die, why didnt she stab Heyun?
N8 - Heyun not wanting to re-enter the cycle doesnt make sense. After killing Cooker Aunt, isnt a normal person's reaction to want to re-enter
the cycle to restart over more logical? If that is the last cycle, he should all the more explain to the police.
N9 - How does Heyun know know that Mengmeng alight the bus willingly and the driver has been punished in episode 12? Previously, Officier Zhang only told them
Mengmeng met with an accident. Only in episode 13, they found out the reason from an online video.

X1 - Why is Liu Tao's Du Supertendent acting so poor? She is useless to the whole plot and should be removed? What she does is only drug test?
X2 - <Minor Bug?> Based on GPS From Police Station to Riverside East Station 22.4km the police only took 9min to reach there? Does it mean they travel at 150km/h?
X3 - <Minor Bug?> From the resume of Wang Xingde, it shows that his driving experience is 30years??? How could it be? his age is only 45!
X4 - Why does the councilior try all sorts of ways not to assist in the investigation?
X5 - Why do the director insert the meal preparation of the molestor? Is it necessary?
X6 - What is inside Mengmeng's HP? Could it contain valuable information about her death?
X7 - What's the issue? Isnt this a happy ending?
