For a person who earned a higher rank sure is dense when it comes to his personal matters

That type of people is not rare really. I have a friend who's a valedictorian yet still can't figure out how to boil eggs properly. So in this situation our mc probably has a lot of IQ and little EQ

Everybody has things they’re good and bad at. Sometimes it’s unbalanced and somebody is really smart, or talented in a particular field, but really sucks at other things. I'm like this when it comes to dating too. I'm oblivious most of the time and when somebody confesses, it’s so inconvenient.
