He was basically hiding their interactions like daily lunch, sharing food from home, regular chats and enjoying movies in office in break time untill her boyfriend reached to me thinking It's an emotional affair. Though the chats says nothing suspicious and both supportive to each others relation but unusual to chat even after working hours. He claims It's his fear as I made insane fights earlier. Though the girl always supported our relation and even helped him to get a good job.
