The Valentine's Day weekend has brought a good boost to the Indian box office, with two major releases, O' Romeo and Tu Yaa Main, witnessing an upward trend in their collections. While Shahid Kapoor's romantic action drama has dominated the charts, the adventure-thriller Tu Yaa Main also saw a healthy jump on its second day. Directed by Vishal Bhardwaj, O' Romeo has emerged as the first choice for cinephiles this weekend. After an opening of an estimated Rs 8.5 crore on Friday, the film saw its numbers rise to an estimated Rs 12.25 crore on Saturday.
