The System Takes Me Back to the Past, at the Cost of Losing Everything

She was once his light, but she was pushed away ruthlessly because she was "too poor". She used poverty as an excuse to break up, just because she didn't want to drag him down, and she silently shouldered the guilt of protecting him. Holding on to his broken heart, he was sent back to the past by the system, at the cost of losing all his belongings and becoming a poor boy again. This time, he is no longer obsessed with love, and is only willing to get to know her again, protect her, and protect her in the most clumsy way, without any distracting thoughts.
