The FL is so hung up on the novel/story she knew or read. Didn't she even realize that by intervening alot will change the novel she knew? Just because it's written or foreseen, doesn't mean it will happen especially when she intervenes from the start ╮(￣▽￣)╭ That's why I'm also not to keen with the FL. Basically groomed someone and then threw him away. What does she expect ヽ(`Д´)ﾉ? She changed lots of people's destinies, obv the MC will also be changed (╯°□°）╯︵ ┻━┻
Maybe this is the reason why their "mucuos membranes" get entangled just like what's said in ch10... Now it makes sense why ginga knows kouchan like to hear clapping sounds... ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
