Hello!!! Am looking for a novel were the MC jumpus into different worlds and in every world he meets the ML. In one of the arc (the one am looking for) the MC is gonna sent to dead but I I remember right he has a week to live so he say that he wanted to spent that time at his home. But every night he escapes to see the ML that is a prince in a jail or hospital because he was hurt or something and get really abrasive(he is poison with black energy or something), so the MC canes every night to cure him. And he did and on the day of the execution the ML save the MC that was gonna be eating by a monster. The MC was gonna be executed because one guy say that MC father was working with the enemy(demons or something), so they kill him and now his son. The MC has light or holy powers, and the other guy is a fake.
