At first i thought tamaki was asexual then it was actually his trauma and his psycho 'not fit to be a mother' mother. His bad mental health is the result of his mothers bad mental health and the bad environment his mother gave him due to to only getting pregnant at such a young age and situation but also not really in the right shape and mind to care for a kid. His mother really need to straighten up and focus on healing and giving his child a safe healthy and happy environment to be.
Im so upset i really wanna see the uke get upset and break this thing off. He'll be the only one getting hurt with this arrangement. I dont want the uke to be the one the seme is gonna settle for just because he cant have the teacher. When they graduate I want the uke to give up then let the seme jealous and run after the uke this time.
