I'm glad that they were able to do this but in reality Izuki kinda just got lucky with Ritsu's response. Ritsu might take it differently and will just get everything down to hell and I see it now (referencing to my previous rant where I question Izuki's decision of confessing to Ritsu despite everything that happened before that), it seems like Izuki took a dive and hoping she'll get it right, like a do or die situation. However as much as I am happy at this reveal, I think back. What's the point of all those previous chapters? I will take back everything I said back then if they can justify those previous chapters after this.
On the bright side, hey I can finally choke this manga without hurting my throat.
