Billlie's Sua, the younger sister of late idol Moon Bin of ASTRO, expressed just how much she misses him in a new letter.

On May 27 KST, the idol visited Moon Bin's memorial space and left a handwritten letter on stationery. The letter reads as follows:

"Oppa, it's me, Sua.

It's raining today!!

I always miss you a lot, but I especially miss you today.

If I could just meet with you, I'd want to smile brightly and hug you tightly without saying anything.

I still love you so, so, so, so much and cherish you a lot.

'Ah-geon-bap-haeng!' [A shortened Korean slang meaning 'Don't be in pain, be healthy, make sure to eat, and be happy']

- Your only younger sibling Sua"

Meanwhile, this is the second letter Sua has left at Moon Bin's memorial site, which was specially prepared by his agency Fantagio Music. Sua's first letter can be seen here.
