I feel like kissing is more than enough, especially when it's being done without Hiromi's consent (while she slept) and with Meguru clearly not taking no for an answer. It sounds like it was going on for a while; their father may have given it some time to see if things would calm down and acted (appropriately) when they didn't.I still wonder how far she went with her sister. Like the kissing on the lips is bad but wouldnt think its so bad that they had to be seperated and not allowed to see each other. So I wonder if they actually went further than the kissing and if they did, that would be really really bad…
