Help Needed - Looking for a story

I need all of your help in finding a story.

I remember reading this story years back on this forum, its on Ariya -

Basic plot is Arjun and Sameer are best friends and in ETF. Roshni is Sam's sister. She has one sided love towards Arjun and she is a teacher. but no one knew that Arjun was in love. He fell in love with a girl when he was undercover as a Karate teacher in a college. Later its revealed that the girl is none other than Riya, who was Sam and Roshni's younger sister. Roshni gets heartbroken, some drama was there, Roshni slaps Riya and Riya goes to Arjun's family. I dont rememebr rest of the story. Can anyone please tell me which story is this? I would love to read it again.

Thank you in advance.😊
