Why is this acceptable but "A Girl & Her Guard Dog" is controversial?

I'm not so sure why this seems to be OK by a lot of people but the other manga is not, especially since this one probably has bigger age gap. Is it because Guard Dog has the guy raising her since she was a child only to fall in love with her later?

But then, not a few people hate Guard Dog for the sole fact that she's underage while he's adult with huge age gap, so the fact that he raised her sometimes seems irrelevance to the controversy. I have not read both, so an explanation would be appreciated.

Well... you already said why the other is more unacceptable than this one. Both have an age gap that we can't just ignore, but the big problem for me in the other one is the "I raises you since you were a child", like... "I raised my girlfriend, so she would like only me", even in fiction that's something that I particularly can't accept, and also that one have more sexual advance, and the ML is pretty more monopolizing and also a stalker.
In this one you will have a ML that is constantly saving the MC from suicide giving her reasons to live for, and he really don't monopolize the MC at all and in fact add more people to make her life more colorful.
That's my opinion.
