Actor Gautam Rode, remembering his 'Suryaputra Karn' co-star Siddhaanth Vir Surryavanshi, said that he was a soft-spoken and well-mannered guy. "He was quite fit so I don't know what happened. There were no health concerns that I learnt about so news is just so shocking," he added. Siddhaanth died after he collapsed at a gym on Friday.
