For me personally, I really like how the pair are both tsunderes and not the violent-bully-type of tsundere and instead is actually the bickering type, they also both started dating in the end which is adorable on it's own. Sanaol. :')
Cute! But missing more chemistry. They liked to argue two virgins who are now in university. Why not show how much experience they have in bed then to donit with each other?
