Tinky (and her family (the angel was also involved)) VS the world

On a sunny monday morning , Tinky finished her mango juice and ran to pack her bag . Immediately as she packed it , mum gave her lunch . Dad asked her to hurry as he was getting late for his work . Tinky managed to rummage all the item needed and left for school . During the first period , maths sir had given a sum to solve on the board , no one could could solve it .......... except for the class topper Tinky . The teacher told her to come to the the board and solve it . The whole class shouted together saying "Nerd , Nerd , Nerd" . Tinky was very upset , she ran out of the hallways towards the washroom , she started crying a lot . A girl who was never in the school went towards her and asked her "Are you okay?"Tinky replied "NO! everyone keeps teasing me as if i am only good for studies and nothing else. The girl said "just beacause someone says something about you , it does not chang who you are",Tinky felt very happy after their conversation. The bell rang and the other girl left in a hurry , Tinky tried to search for her during lunch break , but she was nowhere to be found . Tinky was in a mix of moods when she sat on her bench during 6th period. She wondered whether to be happy that she was no longer upset or sad that she never got to say thank you . Everyone in the class continued teasing her , but.. this time , she did not bother , she followed the saying "Ignorance is Bliss" . After some time the teacher came to the class and started her lesson , at this moment a few bullys in her class made fun of her as she was dressed very formally (with hairstyle matching the school rules). Instead of stopping them or chaning Tinky's place , the teacher started laughing too , while they all laughed at her , the unknown girl who had helped her in the washroom suddenly appeared out of nowhere and recorded everything. The other students saw the girl recording everything and even they started recording. A few people started livestreams on youtube , a few of them stood up for Tinky (Maybe only because the video was going to be viral).Tinky was very happy And started a protest saying "SAY NO TO BULLYING" . After a few minutes the bell rand and the teacher left the class , as soon as he step out , there were 60 or more students standing out of the class with signboards saying "HOW CAN YOU BE SO CRUEL" , "SAY NO TO TEACHERS HOW ARE CORRUPTED , LIKE YOU" etc....... With all this commotion happening , this issue was directly addressed to the principal by a few students. The principal called the security gurads and called the teacher to her cabin , where the teacher had an unexpected suprise - Tinky's parents. Tinky's parents were ready to take action , but......... something was missing , they could sense it , Just Kidding , they knew it , they were at the ending Tinky's parents. They called Tinky and asked her if there was anyone else they had to complain on , the bullys pleaded her not to complain but................ after all that she had been through she had to complain. Even though , unlike others , she did not. The video of the teacher teasing her was viral online , Tinky's parents immediately complained on the teacher for the breaking the teacher decorum and THE "CODE OF CONDUCT" , he was later fired and never rehired . There were rumours that he had left the country and had fleed to a different place . After that day , Tinky never saw the girl again , she searched for her for days and months but never found her.Now , even the bullys knew that Tinky was going to be an inspiration to a lot more people , so they left their bad deeds and focsed on becoming as great as Tinky . After 6-7 months , the girl reappeared , she told Tinky that she was an angel sent from heaven who was very determined to help her . Tinky hugged her very tightly and said "Without you my life may not have been like this , thank you , for everything" . The girl replied "My pleasure , and......... this was all possible because you had the will power to believe in me , i was a mere medium for you to acheive your goal , so, be calm and always help otheres . Whenever you need me , call out to your heart , your gut will tell you the rest " . Tinky was shocked to see that the girl had vanished into think air , but she felt great that she was highly appreciated ". And from that day on , she never failed to believe in her heart and help others , she motivated a lot of other youngsters and became very enthusiastic . 

Now , I want the readers to answer this question , tell me why the underlined word "May" is used instead of "Would"
