If this lovely art belongs to a manga ?

She did the right thing ! I was worried that she would try to hide it, which would have probably led to a break-up. I'm relieved ... now if she can keep Naruse from killing Hakumada, all will be right with the world ! LOL

To be honest Hakumada/shizuka or whatever is being a total jerk and deserves a punch. Don't do that to anyone's girlfriend and especially not to someone you considered a friend or at leas a close acquaintance.
But Im also happy she told him, this is normally a really annoying trope in shoujo manga :P

LOL ... I didn't say there doesn't need to be a confrontation. There does, ... but a fight would probably get them both kicked off the team. Action vs. Consequences. The post I made at the ending of the previous chapter said she should have slapped Hakumada hard right then and there and put and end to it. But that didn't happen, so here we are.
My heart ... my heart failed after seeing chibi Naruse and Hakamada-kun !!!
Kowai !
