Help me with a script

[falcont2t]

first of all sorry for my english, im kind of in a hurry, so i hope you get the idea of what i am saying

well i have this script i have to present for a school project, its almost done but i felt like the introduction was kind of short after i wrote it down
theres a break when the protagonist gets accused of pedophilia, after that, the actual main idea of the film starts, which is bassicaly how a guy gets life itself to a minumun of requirements (talking about technology, social relations etc) and how he grows in his mind this need of getting challenges in everything he does, to become some sort of ultra-man, which is part of a insanity goal of reaching a spiritual new level of perfection.
After the accusation, he gets fired (hes a teacher) and he wont get accepted on any job.
the intro would be something like this:
-the main character (Johá, about 29 years old) goes to the roof of a building and jumps to kill himself (with some monolgue going around)
-a police gets interviewd about the case
the movie goes to earlier events
-he wakes up to realize he fell assleep in front of his pc, takes a shower and goes to school
-some monologue while hes doing a class(the monologues actually have some philosophy going around so they are important) and a female student is staring at him
-the teacher wakes up, tries to get a shower and notices that theres no hot water (monologues again while hes doing all this shit) takes the shower anyway and feels the pain of cold water.
-he is cheking a test he did previosly while the students are talking and stuff, after that he talks a bit with he girl that was staring at him (notice that in the dialogue they have you can tell theres confiance, but there isnt anything that would make you think they have or had some sort of relationship, thats the idea)
-then he goes out of the school and gets intercepted by this guy whose mad because his daughter got an F in his test, he explained to him the reasons(because theres actually a weird situation going on in that) and little by little in his explanation he goes sarcastic and idiotic, that makes the father angry and claims to know whats going on between him and his doller (yeah hes the dad of the girl we previosly saw talking with Johá) so he tries to punch him and johá reacts, but finally the father kicks his ass.

After that the actual movie starts, you think the intro is too short, its ok or needs more scenes? i was thinking on adding something between the talking he has with his student and the fight he gets from the father, i dont know, any ideas?
