You are right! He must have been afraid that Ayan had somehow found out and was going to expose him.

I wonder how come not a single student knows what actually happened to Dika. It does not seem right. Many of them are nosy, and Dika was a beloved teacher – at least one of them must have tried to find out how Dika is doing at the other school and realized that he does not teach there. I feel like Namo might know the truth.
Another thing: Khan and Akk are so observant that they had noticed Dika's pot of white roses. If I am not mistaken, Ayan's notebook used to be Dika's. Khan or Akk, or both might have seen him carry it around school. Maybe Khan stole it to learn how Ayan and Dika are connected.

I added and then deleted the following:
In this episode, Akk opened up to Ayan about having been a violent, misbehaving student because he was made fun of. If he punched people, he was a rulebreaker, and rulebreakers get punished by the "curse". I wonder if something happened to him. Maybe he really knows more about the curse than he lets on.

This is my original comment:
When Ayan screamed that he can tell everyone what the school curse is, he proved my suspicion that he knows way more than he lets on. You know what struck me as weird, though? That Akk punched him immediately to silence him.
I mean, yes, Ayan was going to say something that might be damaging to the school, but the lightning speed with which Akk reacted was suspicious. He has been prying into everything Ayan is doing so persistently that he must be curious to learn what Ayan knows. Why punch him in a moment when he is emotionally unstable and could finally spill the beans? This raises an interesting question: does Akk also know more about the curse than he lets on and what precisely was he afraid to hear Ayan say?

Yes, I removed the second version. Should I post it back? My original comment is further below in the comment section.

I just rewatched the scene in which the class is wondering who stole Ayan's notebook, and Khan says: "Wouldn't it be nice if it was a who?" I am starting to feel like he is directing everyone's attention away from real-life suspects and toward a "curse" on purpose. I think that he is a character with a hidden agenda. Even his nickname, Bruce Wayne, if he indeed is the person who texted Thua, is telling: Bruce Wayne is known for secretly assuming an alternate identity, Batman, to fight crime.

I wonder for how long Ayan had been suspecting that Akk is behind the curse and how he figured it out.

That's a great theory. He is suspicious, but at the same time he does not strike me as a bad person. It seems like he knows more than he lets on. Maybe he indeed is a time traveler.

I also suspect Khan. He is annoyed with Ayan because he suspects him of influencing Thua. He is obsessed with the curse. In the scene from episode two, in which Akk notices Ayan's writing in a notebook, Khan is there too. He must have also noticed that mysterious notebook. He is nosy.

Yes, you are probably right. Thua does not have a motive. I wonder who can have access to extra keys. The prefects?

Indeed. I have watched so many more famous series with higher budgets that had way more predictable twists. Kudos to the production team.

He might have had a crush on Mes, but not necessarily.
I think that many of us have admired someone for who they are and for their accomplishments. It is especially common in high school – juniors look up to seniors. I actually had a similar experience to Akk’s. Before I became the leader of the Red Cross club in my high school, I met the previous leader. He was my senior by three years, and he was impressively smart, hard-working, and well-behaved. I was astonished by his work ethic and calmness. I admired him so much and aspired to be like him. I always listened to the advice he gave me. He was like some kind of an ideal. However, I did not have a romantic crush on him. :)
I would love it if this series portrays Akk's relationship with Mes as that of a young student looking up to an accomplished older one – something akin to Ayan's looking up to Dika. Not everything has to be about romantic attraction.

The teenager line hit too close to home.

I agree with your every word. :)

Yes, they are okay. They are just expressing an opinion. There is no reason to give provocatively rude replies.

I agree with you about Apo. I also did not like his acting.

This would be a great scene.

I also thought that it was Namo at first, but then I decided to look at the hand and saw the watch.

I agree with you, but Akk is like that – aggressively curious. xD

This is precisely why he might be behind the theft. This would be a great twist.
