this novel abt a villain system telling our fl to mend the relationship with the og couple bc she is not high level enough to bully yet. the og couple always have A LOT OF misunderstandings and they break a lot of time. this is an angst og novel so the fl died bc she gave her soul to a ?sword? to the ml so he sealed the demon king and our fl is corrupted too so she got sealed by him. i remember one line from the novel one is dead one is wounded the novel cover is just red with texts and it have around 45+ chapters
maybe the villainess wont let the main leads break up? the cover is a but different tho. if it is this one it hasnt updated since april lol
i only chapter 1 i pressed f 4 while reading. from what i know its just that the villain system told her to mend the relationship
