Some of 2PM's most dedicated fans, also known as Hottests, came together to celebrate the boys' 2nd anniversary by completing a variety of tasks, one being the recording of an entire song! Titled This Heart Of Your, the lyrics express Hottests' never-ending love for the group, and is done using strong words, including being written in 3 languages (Korean, English, and Thai). One of the biggest objectives of this project was to unite fans, and to work together to show their appreciation of 2PM. It definitely succeeded, and acted as a great response song to 2PM's Thank You If you're interested in participating for the 2nd part of the project, Giving Back2U, be sure to check this out. The plan is for as many fans as possible to participate in 730 hours worth of community service events to celebrate 730 days (or 2 years) since 2PM's debut. Also, if you have a Twitter account, you can help celebrate by including #2yearsPM in each tweet. Happy 2nd anniversary 2PM, and many more to come!
