Idk why ppl say they didn't liked it or it was unnecessary for them to make an OVA, cus i liked it Yoshino going through flashback and being happy at the end was satisfying to watch and the 1st half of the episode was kinda funny to watch so yeah i liked it . Sad the animation has changed in S2, i haven't watched S2 yet but as i saw from the trailer and stuff i noticed the animation has changed and i would say the older animation looks way better and good, gonna watch S2 soon so will be droping a review for that too!
