I heard that the system has been very arrogant recently, and the author is empty frost white

My name is Sangong Xun, I am an ordinary high school student, although I am a time-traveler (these days, the identity of a cross-traveler is not easy to mix at all), but I have always calmly faced all kinds of storms in life——————

calmly crossed over to a seventeen-year-old girl,

Calmly faced an old girl who was very bad with me,

Calmly managing a big brother with a split personality,

Calmly take care of a mentally aged (9) mother,

calmly went to school for a lifetime,

calmly lived a life with few pot friends,

calmly listened to the voice that suddenly sounded in his head-

"Hello, No. 2B41254625, my name is System Jun. Thank you for your first meeting. ”

Sangong said that he couldn't calm down~~~~~~

P.S: Ahem, there's a change tonight.
