A physics PhD student transmigrates back to high school. So were all those years of work for nothing? Lin Zijun wants nothing more than to return to a normal life, to the right point in time when he made all the reasonable choices: freedom (after a breakup), studying one of the hardest subjects (even though he doesn't like physics), and landing an enviable job (though not his ideal career). His first love and his high school roommate will get married in the future. So what? He'll watch with indifference. A genius high school student has no pressure in life. So what? He's good at handling pressure. The care and affection of close friends and family are right within reach. So what? When he goes back, all he'll have to endure is a little distance, a time difference, and being completely misunderstood... But after spending so long enjoying the good old days, he can't bear to let go of his old love, friendships, and family ties, or his new studies. Lin Zijun starts to panic. Could the choices he once prided himself on as rational and optimal actually have been wrong?
