Please help

Hi. I am looking for a set of Arshi works- all by a single writer including FF's, OS and SS.

1.FF- Shahi Gupta is mentor of Arnav. When shahi gupta dies, arnav becomes the guardian of Khushi and Payal. Payal is not blood-relative to khushi. Khushi and Payal and doctors. Khushi knows arnav and loves him all along and payal, aman knows it. Aman and payal love each other. Arnav is unaware of all this. Shyam/Rahul(Not sure about the character name of Anjali's husband) is a good guy but Anjali divorces him due to some misunderstanding but they have a son. Shyam and Arnav are very good friends and brothers. Akash is married to some Riya or other girl who is the reason for all the issues and she wants Arnav.

This one is incomplete i guess.

2. FF- Arnav and khushi know eachother since childhood and anjali is his younger sister, they love eachother. Arnav's mother raises khushi also with a caretaker kaka... She dies due to some conspiracy. Arnav unaware of the reason of death but is following her words of going to a place to live. Arnav's mother sends him to kaka where khushi is also there. They start new life. Aman becomes his friend and they start a company.

This one is completed.

3. OS- Arnav is in army and He resuces khushi and her family from some natural disaster. He gives her a rose in return while she gives him food.. during her temporary stay at shelter. Later all women are sent away. Later Arnav finds her and they get married.

I can share few more ff details but not sure anyone remembers it.
