Rebirth of the Concubine's Son that becomes respected (BL)

It started out nice, but then that...... not really sure if there would be really so many twists and turns in royalty.... 

I'm so weak for this type of setting... Curse you cuz I know I'll have a hard time MTLing this *crying like a dying seal* 

I've been quietly watching this threads but now I can't really contain myself. Spoilll me pleaaaase!!!
And thank you for the wonderful recommendations and spoilers.
The ML seems more likable to me than the MC. I'm kind of surprised because in most novels it's usual the opposite. I either drop it because I can't stand the love interest mistreating mc or I feel tired of the wishy-washy personality of th MC. Now for the billion question: will MC redeem himself towards the ML? I hope he falls in love for him not because its convenient or due to being grateful. 

I know, reading MTL is frying my brain.
And I didn't know that, thank you~ And for the others spoilers too!! That helped me understand the MTL~ 

the chapters are pretty short imo, so the scary 200+ chapters isn't so scary anymore xD 

Is this being translated??? Where's the NU page??? 

I'm not really sure of how to think of this plot... It's a plot of revenge and fixing mistakes.... i mean ik C. authors like that setting... but welp dunno... i guess i will read it for that mc goes back in time and is a baby. 

Mini spoiler dump~

-okay, so Queen Mother is actually good for ML because she keeps close watch over him. I got that part wrong, MC must be weepy at idea of starting over again with ML or thinking about potential enemies of ML.
-royal family (Emperor, Queen Mother) thinking about education and potential playmates/studymates for the princes. MC is elected to be among those going to the palace.
-when MC receives news, he's at first not very happy. Then his tutor (grandpa) mentions that ML will be there and he lights up. LOL. Even old tutor catches on, even though MC spins some BS about meeting the 'light of the Queen Mother's eyes.'
-old tutor grandpa worried about MC getting caught in palace struggles
-MC determined not to let ML waste a decade conquering the world/getting the throne. Already thinking of hubby, huh? XD In last life, MC didn't manage to join this elite study group, so MC didn't meet ML that early.
