@anikaniko i agree, but well, there two option, running away or be stronger
But Risa is a feminim girl, she is being pampered with fukami san and if she being protected again and again, she will think its her fault and she will think that if she not around him, fukami san will safe
so that why she choose to run away
But actually if risa choose to be stronger like studying self defense, i think that will be cute too,cus risa is a hardworking girl
But again, maybe she didnt thought about it
So its natural for her to run away
Im sorry, just want to share my opinions😂
