Su Jin woke up and returned to the third year of high school. He activated the system of a thousand times effort (which can be upgraded) return (later, favorability and money can also be upgraded). All efforts will be rewarded with double effort return, starting with a maximum of a thousand times. (A thousand times is just the beginning)

In this life, Su Jin’s efforts will no longer be in vain!

This time, he will live out his true self!

The regrets of the previous life will no longer be regrets!

Those who have been missed will no longer exist only in memories.
