Bubbly actress Hansika is going ga-ga about a die hard fan. She has got millions of fan mails, messages and many more. One particular fan's abundant love has caught her attention. Hansika narrated this amazing story to a leading daily. She said, “There was one guy who used to send me letters written in blood. It was quite shocking. What makes people admire us so much? I used to get a lot of those letters but they have stopped after I changed my home address. I tried contacting that fan, but could never succeed.”
