I'm happy you enjoyed the update. And you are not late, it was only published on Wednesday!
The idea about Erika's scene was romanticism. After her two last boyfriends being dicks, she deserved it.
Lately I get some comments about the updates feeling short, when every update is bigger than the previous one. I don't know if it's because the players who comment on it don't follow all the girls' paths or if they are so engaged with the game and the girls that it feel short for that reason. I hope it's the last one
Calling the MC old is already a tongue-in-cheek joke that will happen from time to time.
