SHINee's Onew isn't just a singer, he's also quite the smartie. This idol leader was a guest on a recent recording of SBS Shin Dong Yup's 300 where he revealed his grades from high school. During the recording, the 300 audience members, who were all under 20-years-old, talked about how happiness can be found from good grades. Onew commented, "I'm actually really shy so I never thought I'd go into the field of entertainment. But in high school, I started to practice my singing. But I also studied hard. In my junior year of high school, I came in second place in the whole school [in terms of grades]." That's pretty impressive, don't you think? The episode airs on the 24th.
