I just finished ch1 and IT IS ALREADY SO GOOOOOD!!! The length of the chapter is just right, - not too long not too short - the characters LOOK SO FKN GOOD I AM SIMPINGGGGG FOR NAGASE (OMG I GOT A NEW CRUSH), nagase is seriously caring and loves niwa and that is really wholesome and cute<3 Like deadass i've never read a manga which i commented on already just from the first chapter. This is some good shit.
