So when I first discovered this OVA an hour ago I went to buy ice cream then took a shower to prepare both physically and mentally.
Honestly, I have mixed feelings about this OVA. During the first half of the episode I felt betrayed disappointed and I basically thought this wasn't the Kayguya-sama I know.
However, during the second half I felt kind of nostalgia although I watched the third season when it aired not too long ago. The second part was usual that I actually felt relived.
In conclusion, if you'd like to feel betrayed then nostalgia for a kind of "Mixed feelings" feeling. Just be careful! The first part is very inappropriate, especially regarding to the rest of the series. If you just want to feel some nostalgia, go watch from the second half.
