Exactly, I think many people confuse what rape is... Yes, he kind of influenced him, but he was very careful and never was the MC scared and the most important thing the MC never expressed regret and never felt like it was rape and that's very important.
Yes, there wasn't explicit concent, but there are times that there won't explicit concent, you have to pay atenttion to see if your partner is into it. To me there's a very clear difference: if the partner is clearly forced and him saying stop in a scared and disgusted way; and if the partner saying stop becase they are a masoquist or a tsundere and they don't express themselves well.
In this case the MC is clearly someone that is scarred emotionally, which is why it never ocurred to him to see the ML in that way, he was simply surprised by everything so the ML made sure he felt good and had fun too. Is their relationship healthy? Hmmm, I don't know because I feel like both of them weren't loved by parents as a child and haven't really had healthy friendly relationships, so they may struggle with the emotion of love and they will probably struggle to define their relationship, maybe the ML will hurt the MC emotionally in some way, it's possible. That's what happens when you have sex before you understand your feelings. But it's not rape...
well the mc is just wrong for tricking ml to watching horror in the first place but ml is a rapist bullet fragment scab bitch who probably deserves it so im on no ones side
