Rain's younger sister updated her minihompy recently, and shared a letter from Rain with his fans. On October 15th, Rain's sister, Jung Hana, revealed that she received a package and a letter from her famous big brother. She wrote, "A package came today. I didn't have any thoughts about it since receiving it but after reading the letter, I cried. He wrote, 'You are my most loved sibling in the world'...He also told me to give Baekgu [his dog] a bath which caused me to laugh hysterically. Haha. He said, 'Lock your doors, be careful at night, be careful of cars'...I'm doing really well so I told him not to worry." She later added, "I feel more secure because of his letter. Even so, he naturally adapts to things well and his will is strong. He's the kind of oppa that does everything well!...Anyway, to all of his fans: oppa is doing well so don't worry about him too much." Relieved, fans responded, "Thank you for telling us this news! I'm glad to hear he's doing well", "Please keep us updated often about any news from him!", and "You must have worried a lot since you're his little sister! Thank you for keeping the fans updated!"
