Junsu receives Valentine's chocolate from who?

JYJ's Junsu seems happy and proud to show off the chocolate he received this Valentine's Day.
Who made him happy?

It's none other than his sweet hyung, Jaejoong. Junsu shares proof shots of the chocolate through his twitter account and wrote,

"I received chocolate..from Jaejoong hyung. Makes me shy.~~"
"Ooh my~>_<It's rose........my face has turned red."
"Close up shot..hee he bough it from department store. ke Thank you hyung"

Jaejoong is a sweet and thoughtful hyung, isn't he? Do you want to get one form Jaejoong too?
