On the June 5th episode of SBS' 'Strong Heart', INFINITE's�Sunggyu revealed that he's had a lot of free time because of his recent hip injury.

Sunggyu shared, "To be honest, when my fellow members had very hectic schedules, I had a lot of free time. I went to the hospital to check out why my hips were hurting, and the doctors told me that it was because I was lying down too much."

"When members Woohyun and Sungjong appeared on 'Strong Heart', I was at home watching the program. I was lying down improperly then too," causing laughter on set with his confession.

Sunggyu also comforted SECRET's Sunhwa, who is concerned about her individual activities, by saying, "When there is a member who is getting the spotlight, there is also a member who is lying down at home," giving his two cents on the topic.
