Uwah... back to Romantica, eh? I just don't get why best girls like Adjest never get to take any MC's attention and for some reason even the most dense of the damn MC's keep gravitating toward them tsunderes... those tsunderes make me nauseous. Hair trigger responses/ violent reaction toward MC's and all that, always denying attraction and when the MC show interest in another to take in a date, goes to spy and ruin said date. Or some such.
Yeah, I get that they were together in the previous life (typical), and while it's sad she died not much time had passed for him to get over her (unfortunate)
