Mr. Shim's Request

I should go visit Mr. Shim in Folk Town. I heard he hasn't been doing well lately...

At the Korean Folk Town, I met with Mr. Shim, who's a loving father to his only daughter, Shim Chung. Lately, however, he's been worried that his eyesight is rapidly failing him, and that he was worried he might one day become blind. He wanted to buy a pair of Reading Glasses, but the astronomical price tag calls for 300 Item #4031279s per pair, he wanted to borrow them from me. How am I going to find Item #4031279, though?
Ahh, Mr. Shim said I can find it through Retz at Helios Tower...

Item #4031279 (Item #4031279 count) / 300

I ran into Mr. Shim, who was concerned about his rapidly failing eyesight, at Korean Folk Town. After hearing his story, I promised to lend him 300 Item #4031279s. The problem is, I don't have any rice ... but thankfully, after gettin Retz, I was able to get 300 Item #4031279s. As a sign of thanks, Mr. Shim gave me Item #4031280.
