Does he have a cuck fetish or something!? Bro just take her slready ffs.
He wants her to be the happiest ever and works hard for it, she wants him to make that choice for her because she deeply trusts him and wants him to make her enjoy life so much she would want to stay.
The obvious conclusion? Hurr durr find someone else at school. Ffs these type of pathetic men in manga are so tiresome
calm down, lmao xd? His reaction was the absolute best in this situation at this exact point in time. Like, the author couldn't have written him any more perfectly, moreso with what she told him THIS EXACT CHAPTER, lol
She not only is a minor but she just now realized that
she does actually want to experience her youth (which he already did and is WAY past) and that she missed the lifestyle of casually going to school and meeting a lot of new people (which in her own words used to be entering the homes of strangers or having some casual daytime boyfriends)
Ngl, her going full high schooler mode must be an insane turn off to him and it was handled the most plausible and in-character way possible: he lit up and was happy for her as a guardian while shoving everything else aside.
I for one think this was exceptionally well done and the author can go any way possible from here without it being uncomfortable and weird.
You actually chose to get mad at one of the incredibly rare instances (like 1 in 20) of a good "beta cuck" MC.
