Hey mangaka san, doing a 180 on the personality of a character isn't the same as character development... Who is this Alves guy? We're sold for 7 chapters that he has a shitty personality, massive tease, easy to rile up, apparently indifferent. For him to suddenly turn polite, soft spoken, gentle, nerdy, is a bit of an unacceptable jump... No matter if you give him one rude sentence at the end so the MC can go off pouting.
Also, he doesn't have a way to hide her? Really? Two chapters after invisibility spells? Same chapter as a disguise spell? She can teleport and force him to speak his true feelings with a mirror but she can't make her own fake face? Dang, how lazy is the writing here...
