Ok guys I need the title

So, It's an omegaverse manga and its ab two highschool boys and one is extremely malnourished bc he's being neglected (or rather abandoned) by his family for being an omega, in his backstory he had an alpha little brother who used to treat him well but got spoiled and grew up influenced by his family's idealogy. The main lead is like a smart rich kid that beat the omega in the exam board or wtv it is and the omega was mad and after that blah blah blah the alpha goes to his house to check up on him and found out ab his living conditions so he started cooking for him...
