it was good at beginning but later on the quality of plot is decreasing, and the mc is now like a simp to his girlfriend, ingrid

I only read 50 chapters and these story is quite good but i dont understand one thing? the mc dude came back to present time after thousands of years and instead of going to see his parents he told her to wait for 30 days? it was already shown that he host his family in his previous life and instead of going to see them immediately he waited for 30 days and other reviewers are like 'Mc is not naive but he's soo good with his family'
