Harassed by a guy

I don't know what I'm gonna type so please bear with me. Maine similar post pehle bhi ki thi and something similar has happened yet again. Whenever I used to go out, this one guy always followed me and shit but i ignored. Aaj mai aur meri dost baith kar baatein kar rahe the then suddenly he threw a chit towards us, I didn't even notice it at the time but my friend did. Maine use bola ki hilna mat and pretend as if we didn't notice anything. Fir kuch der bad bina wo feke hue chit ko dekhe hue, we got up from there and started going somewhere jahan pe zyada log honge so he won't dare doing anything there. Then when saw him walking with that same yellow colored chit(that he threw towards us and maybe picked it up zince we didn't even touch it). We rushed home but he was fuxking sitting at the corner of the alley when I had to take a turn. Hamne dusre raste se jane ka decide kiya and then saw him approaching towards us from the front(he took some shortcuts). 6 baj rhe the , sunsan rasta tha so i knew that I couldn't go home like this. Us dost ka ghar pas me tha so she said that her brother would drop me off . So i went home and I was like okay, bat khtm. Then bhai meri dost ne call kiya meko and she said ki us bande ne uske bhai ko call kr dia hai, Idk how even how her brother's number. I was literally shivering, meri halat khrb ho gyi thi and my friend then told me that us bande ne uske bhaiya ko bahar milne ke liye bulaya hai. Aur iske adhe ghante bad tk meri dost ne mera call nhi uthaya aur meri jo halat thi... then she called aur usne bataya ki us bande ne kisi common friend ke through uske bhai ka number liya tha and he thought thar i was her brother's girlfriend.. Use bas confirm karna tha ki mai uske bhai ki girlfriend hu ya nahi. Wo unse puch rha tha ki wo teri kya lagti hai(he doesn't even know my name, but knows my surname) ..aur tu kise bike pe lekar ghum raha tha and unhone bola ki meri bhen hai tera kya jtaa .... all of this was happening at 8 in the evening, meri jo halat khrb hai. I can't even describe. Maine ghar me bataya and father is literally going to kill that guy tomorrow. I'm literally so scared right now. Agr mere papa ne use sach me zyada mara to wo kahi piche na pad jaye hamare and turns out wo idhar ka hi hai. Kal chemistry practical hai school me and I can't sleep study . I can't do anything. I'm just crying. Her brother was in so much danger just because of me, wo banda 4 5 aur bando k3 sath tha in a secluded area jaha par usne dost ke bhai ko bulaya tya. What if it happens again. Bhai meri dost ke gharwale kya soch rahe honge mere bare me... Kal practical hai, 15 din me jee. Us bande ne kuch galat kar dia gusse me aakar to kya hoga
