How to Save a Time-Limited Young Master

I dont know any but the prospect of immediatly telling someone (anyone) that you are reincarnated or got isekai'ed would definitly brand you as crazy and would not make much people happy tbh, because telling would lead to A LOT of plot issues and it would be very annoying to read since now the MC would have 0 advantages and/or 0 friends if we go by the usual pattern of the manwhas. It's best to be revealed AFTER trust has been built rather than first. For example, a good manwha is something like MY mom has a marriage contract (not exactly the name) but the Mom reveals to the Reader that she remembers and to her daughter (but she doesn't get it). It gives her a HUGE advantage on the plans she has. So, yeah... Sorry, huge text but basicly: MIght not be a good plot for lots of readers :?
Expect few more months before mc fight conclude.
Why is she not brave enough and defenitively leaves this hell?
Whahaha
This is so not normal, no matter how many times Korean simps write this. Even if you don't do anything the first night, sleeping next to each other is not an issue what so ever. They're freaking married and even then they still can't show any kind of affection. It's pathetic really.
