It's fully translated in English now, cool!
I have such an odd feeling towards this series, these revenge for being cheated on plots are interesting but Koibito Swap treats everything so lightly, the same way I feel happy for Yuusuke and Kotone finally hooking up to move forward from their shared pain, I feel iketani and Kayo don't seem to be bearing the true consequences of a teen pregnancy, moreso Kayo who tried to fool hers and Yuusuke's family into believing the baby was his, look at them trailing Yuusuke and Kotone like silly goobers at the end, it kills the catharsis factor.
Edit: Looking further into this matter I now know the Manga version streamlined and outright cut many plot points from the Web Novel, the Manga version is verifiably more light hearted, thus the feeling I had wasn't just a personal impression, the catharsis I sorely missed is in the Web Novel.
The credits page in this final chapter personally thanks
@Cross-21-, rightfully so, go read his comments, he details what was left out in the manga version.
