I've read this. This novel will make you cry (just a little) hahaha Iirc, the arc are: Overbearing President X Poor MC Illegitimate Child turned into a Heir X President MC Emperor X Minister(?) Child of Enemy X Doctor MC (foster dad) Marshal X Infected Human (traitor) MC Demon X Monk Not related blood Uncle X Nephew I don't know if the order is right or not hahaha. Btw I haven't finished it so I don't know how many arc are there. I don't know if this novel is BE or HE because in every arc that I've read, MC died 10 days after his mission is completed. Poor ML. MC argued (to the system) that he became a scum in the first place is because he cares about ML. After MC left the world, his body is still there, and it is operated by the system. This is actually a free promo. And MC is the first one to get the promo(?) Usually after the host left, the body will be died/disappeared etc. So, MC worried that ML will get hurt etc. After MC comeback, his mission is to reduce ML's blackening point. After the point is 0, system will tell MC that he will have 10 days time until he left the world (this time his body will died). So, in every arc, the cycles is like this: ML saddened by MC's betrayal 》 met MC again 》 a little dog blood drama 》 so called 'truth' behind every MC's action in the past 》 ML feels guilty, apologized to MC》 reconciled 》 blackening point became 0 》 MC left the world (dead) 》 ML sad again. I think the story is good, interesting and easy to MTL. But at that moment, I need a mood booster, so I drop this novel and read a fluffy one.
