Please take a look at this laptop

I am looking at laptops in the mid-1 million won range.
For my middle school son's studies (hopefully) and casual gaming;
And for my work during the weekdays (standard tasks).
For these specs, a Lenovo is 1.78 million won during the Black Friday sale.
The specs seem sufficient, but Gram and Galaxy Book models are expensive.
I plan to use it for about 5 years, so please advise if this is a reasonable price.
