we see MC dropping the sword and started punching the tiger on stage. The stake here is that they will ruin the performance in front of the new students, a stake that has been set up from the very beginning - that's one conflict.
Another conflict is that, earlier in the episode, tiger wanted to drink a vile of rabbit blood, that he apparantly got from a delinquent senior, as a doping for his performance. We see later that his is too nervous to even remember the blood until it's too late. MC went bananas because of yet another conflict. This time it's both inner as well as outer. In ep 1 we see MC trying to resist his carnivorous instincts to eat the rabbit girl, after which he manages to snap out of it although he scratched her and left a wound all over her arm. And then another scene later he doesn't want to see her cause he still feels bad but his drama club needs roses for the set and she happens to be the only member of the gardening club. Also, for some reason she "apparantly" can't remember where she got the scar; the show still haven't revealed the truth yet. And because of her previous relationships where every boy she hooked up with immedietely dumps her afterwards, she thought that he was here for sex and long story short he ran away and things between them are even more awkward. Nevertheless these experiences plagues his mind ever since. The rabbit blood really ticked him off and because of how offended he is now the tiger knows that something is up with him and a rabbit. If his secret is uncovered, the whole school will now know that he cannot control his carnivorous instincts, mind you this takes place very recently after the death of a fellow classmates lamb who was also in the drama club and was killed by some sort of carnivore. That, as well as the fact that he has relationships with a rumoured slut. This is conflict on top of conflict.
Oh and how did they get there in the first place? Well the tiger is supposed to play the role of one of three antagonists (the role MC is now forced to take because of lack of substitutes). The role of the protagonist is played by the red deer with a superiority complex, and he broke his leg so now the tiger has to take his place. How did this come to be? In the first episode he wants extra training on the stage despite explicit rules stating it's not allowed. He had set up MC to guard the situation and warn him if a teacher comes near. This is where MC couldn't suppress his carnivorous instincts for a split second and wounded the rabbit. Back to the red deer, he slipped and twisted the ankle although he is still able to walk. And guess what he did? If he went to the hospital the teachers will know that he is breaking the rules and so he hid it this entire time. In the third episode we learned that his superiority complex comes from the fact that he hates the fact that he is a herbivore and that carnivores are always on top of the food chain and so he wants to make a point that herbivores can be superior to carnivores. But really, he cares for everyone. We can see this by his great voice actor and amazing CG emotions within his face to deliver this incredibly subtle behaviour. Later on with the first day of the performance (the performance is set for two days because the new students come in both of those days) he barely manages to hold himself until the curtain just dropped and the new students didn't have to see him faint.
What's the resolution? Everyone doesn't like the actor for the new protagonist. The audience is a mixture of fans of the drama club mixed with the new students. They know that the red deer is not playing the protagonist and so is dissapointed. But then when MC fought the tiger on stage off-script, the fans of the drama club knew that something is going wrong. And what happens next? The red deer just barely manages to recover to be able to walk again and improvised the entire ending by making up how the tiger is a fake protagonist and bla bla bla and everyone cheered just cause they're happy to see the red deer playing the role again rather than the greatness of the story.
There are a lot that I skipped over as well so you have only been spoiled half of all the things up to ep 4.
So with this we have conflicts layered on top of conflicts. The "MC hurt rabbit" conflict and "rabbit misthought MC was there for sex" conflict builds up into "MC fights tiger" conflict which couldn't exist if "red deer practices against the rules" and "red deer has superiority complex" conflicts didn't exist and the latter of the previous two was built up even more upon the "herbivore was killed by carnivore" conflict in the prologue of the story.
