The grumpy old man may have fallen in love with G.E.M. because his children like G.E.M., so he naturally became a fan of G.E.M. Seeing grumpy grandpa singing G.E.M.'s song Bubble shows that grumpy grandpa is also a die-hard fan of G.E.M., so G.E.M. will respond to grumpy grandpa in Northeast dialect. G.E.M. also responded to him with his grumpy grandfather's actions, which was very cute.

G.E.M. is lovely and her singing is beautiful. Many people like to listen to G.E.M.'s songs. In fact, I like them very much, and I downloaded one of his songs specially, but I am not as good as a grumpy grandfather who is nearly 80 years old. After listening to it for more than 30 times, I didn't remember a word. It's also my fault that I'm tone-deaf. But G.E.M.'s image is still very good in my impression. Some time ago, I saw three-year-old G.E.M. reciting Tang poems. So she stands out, because she is smart.

It is said that G.E.M. can be summoned by collecting seven stools online, and it is enough to see that his grumpy grandfather is an old man and fight for his idol G.E.M. Even at home, he collected seven stools, but his efforts finally got a response from G.E.M.. Seeing the video of G.E.M.'s response, we can see that G.E.M. dares to shoot a video without makeup. It can be seen that G.E.M. also likes his grumpy grandfather very much. Bad-tempered grandpa may like G.E.M., because G.E.M. prefers fans. Generally, older people don't like idolization. Even idolization is idolize's age. Grumpy grandpa can become a fan of G.E.M., probably because his grandson or granddaughter likes G.E.M. very much.

Grumpy grandfather watched his grandchildren chase their favorite stars every day, so grumpy grandfather gradually fell in love with G.E.M. Moreover, G.E.M.'s voice was very crisp and pleasant, and his grumpy grandfather also called G.E.M. to get married quickly. It is true to love his idol G.E.M. as a granddaughter.
