Tsundere
Periodt. Yes, the 't' is essential! Tsugumi(uke) is a very strong-willed omega that doesn't buy into any of that sexist sentiment, he said," no thanks, on the omega inferiority complex!" Megumi(seme) is very protective of him and it warms my heart.
10/10
This couple is honestly the cutest. Haga, an omega, is obsessed with finding an alpha with a perfect set of teeth. He has a bad habit of collecting alpha's teeth and gets caught in the act. While in thee slammer he sees his ideal type, who is an officer. Their dynamic is *chef's kiss*.

The seme still holds a grudge against the uke for mimicking his favorite anime character back in middle school. Was what the uke did that bad? No... Is the seme just being petty? Yes...But I digress...The uke is an omega and goes into heat after the two have just gotten reacquainted(i.e. the seme being like i didn't forget what you did in middle school or sum tsundere ish like that)
