It's not a problem just choose whichever translation you prefer. Having bullshit drama for fan translations is so fucking stupid, it's fan works you aren't paying for unless you donate.
I get the vibe that the author thinks he/she should insert more shounen stuff into the comic. It was noticeable with the abundance of fights in the early she-who-shaht-be-named arc.
@nansakana I imagine that the editors wanted the romance to progress more. Author probably also mellowed out a bit, cus i doubt he is as super passionate about doing gags about bullying a teasing for 3 years then he was at the start.
