[Akitsuki Itsuki] Itazuragokoro to Koigokoro | Mischief and Love (COMIC Kairakuten XTC Vol. 4) [English] {QBtranslations}

They actually did promise to get married when they were kids, she acted like she made it up so he'd react like he did, and now by tricking him into getting her pregnant they HAVE to get married... holy shit the mind games...

Could use a sequel

That "Just kidding. Fuck you!" killed me xD

The boss levels are too high in these guys

So did they promise each other to get married or not? I'm confused...

Well that escalated quickly
