I hate it when ML's act all high and mighty being like "oh I'm gonna solve everything myself I don't need your support" and then later they'll be the one breaking down and hugging their s/o. Like. Boy.
I'd say I'm sick of this happening in MANGAS but because this happens in real life and I'm hella salty:
Gaku, my boy, you can fuck off with your nonsense. No one forced you to date. Everyone has dreams and goals they want to achieve, and plenty of people achieve that without being assholes. Do better or break up if you can't do the bare minimum of treating your partner with the God damn respect she very well deserves.
The amount of love I have for this manga cannot be quantified. Thank you author, I pray you live a very nice happy life.
