My Darling, the Company President Vol. 4 (Kodansha, 2022)

Thanks to Sakura, the younger man who is both her former personal student and current company president, and his endless jealousy, Mihane finds herself in a mini-spat with him while they're off on a southern island. While it does delight her that he's jealous, the two somehow end up parasailing while their feelings are still at odds...?! He leaves hickeys as “punishment” and then quasi-pops the question to her with a mini-proposal! Mihane finds herself happily drowning in the endless love from the younger company president, but then a second young man makes a rapid approach on the scene with his sights on Mihane... Her heart's pounding around the clock!
