I’m out here about to start reading this but I spoiled myself with the comments and last chapter lol my fault. I’m gonna read but can someone pls spoil me further. When top said he had sex with that girl Yuna “before he developed feelings” for the uke, does he mean that he had sex with Yuna as in while he and the uke were already doing all the kissing and stuff….and he just fell in love for real later on with the uke? Or does he mean like he had sex with her before he actually got involved/interacted with the uke about having no experience and wanting to learn.

If you’re gonna say just continue reading, I won’t till I get my answer ( ̄へ ̄)
