NO NO NO NO NO NO NO
I will NOT let you NTR best boy like this. Especially when they just had a one-night stand and he's clearly better than this deadbeat. At first, I thought she was being a little mean at her former lover in that he tried to commit suicide by drowning but regretted it (those decisions are often in the heat-of-the-moment and instinct takes over, but she seemed rather easily persuaded to jump on board with him) but THIS deadbeat that extorts money just from his looks is NO GOOD. Get the guy with the stable career and feel in love you you naturally, not this gigolo.
Also the Valentine's day special is chapter 14 of volume 2, so it's 2/14. That's cute
