Tbh yeah... even if Shio said she wanted to start slow. From how the pannels were drawn, it feels like Ran was silently waiting for her responses and reactions, she isnt even saying no or look away, or try to push him off. Idk I just cant blame Ran in this. Im already set on being pissed at Shio'e wishy washy atitude.
And pls... she kissed him back, and was even on top of him, she's clearly want it too... wth
