well this is a main problem in a lot of romance manga (yaoi or not). At the beggining i was angry at how stupid the characters were for not actually talking and solving their problems,but after searching a bit i found out that this is an actual problem for japanese people. they don't talk to each other,they don't reveal their problems to other people,they don't show disconfort and all that gets passed on stories like this. And also around half of the population are actually virgins,and no i am not kidding,so ofc a lot of mangakas don't know how an actual relationship works.
IMO both of them have their faults.
Sensei indeed shows his love and possessiveness over Midori. But rarely does it come across as how he probably wants it to. Midori seems to be the type who needs reassurance that he is truly loved by someone like Sensei. We, the readers can see that Sensei truly loves Midori, but sometimes I feel Midori is too hesistant to trust in Sensei's actions alone.
Midori clearly has feelings for Sensei but is so damn hesitant and shy that he cannot properly convey them. He lacks initiative in an obvious way, but we readers can see how he cares for/loves Sensei in ways that are not obvious, which maybe Sensei doesn't really pick up on.
BASICALLY THEY SHOULD USE THEIR WORDS.
Sensei should stop pushing so hard and Midori should honestly man up and be vocal about what he wants/feels.
And they should each verbally state their feelings, goodness ( ̄へ ̄)
