There is no factual basis to a romantic love story between them. They were bandmates in One Direction, and they had a professional relationship. Their interactions were mainly within the context of the group's activities, like performing, recording music together, etc.
One common theme is their relationship. Writers often explore the different aspects of their real - life relationship or create alternate storylines based on it. Another theme could be their rise to fame, how they dealt with the pressures of the music industry while being in a relationship.
Probably their close relationship as bandmates in One Direction. They were often seen together, sharing moments on stage and off. Fans might have misinterpreted their strong bond and friendship as something more romantic.
It was real. They collaborated on a song and during that time, there were reports of a romantic relationship between them. Their chemistry was evident in their musical collaboration and they were seen together on multiple occasions.
Well, Tumblr used to be a great place to find fanfiction related to them. Some fans would post their works directly on their blogs or there were communities dedicated to sharing fanfictions. Also, some official fan clubs or forums might have sections where fans share their creative works about Perrie and Zayn.
Since I don't have any prior knowledge about Mohit Malik and Aditi Malik's relationship, it's not possible to accurately tell their love story. However, generally, a love story might start with an accidental encounter. They might have shared common interests which brought them closer. For example, if they both love music, they could have met at a concert and that could be the start of their journey. But again, this is just speculation as we don't know the real Mohit and Aditi Malik.
It depends. Without more specific information about what 'Malik' refers to, it's hard to say for sure. It could be based on real events, or it could be purely fictional.
It's possible that they met at a social event like a community festival. Mohit might have noticed Aditi across the crowd because of her beautiful smile or unique style. He worked up the courage to approach her, and they started chatting. They found out that they were both volunteers for a local cause, which immediately gave them a connection. From there, their relationship could have blossomed into a love story.
