^If I had to guess, I'd say that, even if the pairing is very cute, looking at them may bring an overwhelming depression due to the impossibility of realization. At least for me, when getting close to the date that the new series would release, I decided to re-watch the old one... I got so sad that I couldn't start the new series to this day. (In doubt, I just spoiler tagged basically everything, but let me know if it was unnecessary)
