I don't think any line and scene combined, I've read in any manga so far, has turned me on like the last panel in this chapter has. Imagining a hot girl pressing you into her chest while she whispers into your ear, “I'm not a good girl… I'll make you obsessed, so much that you won't be able to live without me.” I'd be absolutely done for, doomed and blessed at the same time. Kinky with a dash of slightly crazy seems to be my thing, even in irl.
Now we gotta see the hero aka the best friend's confession next chapter I assume. I like the straight forwardness and MC actually taking it seriously without being ultra dense (so far). We need more of this in romcoms, i'm so tired of dragging everything out with misunderstandings, dense MC's and girls that just get flustered and say baka when they're about to convey their feelings. Please, for the love of god, Japan.
