It's early yet, but I took the younger bro's "like" for the older bro as "I'm indebted to you forever for paying attention to me" and not "love love love LOVE".
The older bro is probably just a controlling SOB.
yes it reminds me of another yaoi that the older brother made it so the younger brother couldn't live without him. So the younger brother might break free sooner or later but I wish they would update it all at once so I don't feel anxious.
I try to resist reading anything new. I prefer to start when there is at least 3/4 chapters so the wait isn't as bad.
So it has been confirmed that they both have a thing for each other, the brothers i mean. I don't know how this is going to end but both brothers are crazy
