Trying to remember a manga series I first saw a year or so ago. It was like an anti Nagatoro-san series

It was about a timid guy with a seemingly domineering girlfriend who kept teasing him as an act in order to force him out of his shell. It backfires when he does finally get a backbone only to confront her for 'bullying' him and break up with her. He then basically confronts an entire harem of girls and crushes them under the belief that they're bullying him rather than in love with him (one was a girl at a tsundere themed maid cafe who gave him extra attention because she loved him). The first chapters are basically him going around breaking girls hearts because he misreads their intentions.

Pic not the series in question obviously
