I'm looking for a certain manga, can't really remember that much, but it has a certain scene where the senpai (actually, nto sure if senpai, but a kind of mature person who can totally do anything), let her kouhai (not sure if she is really a kouhai, but she is the kind of person that is very clumsy) to straight her hair with hair straighteners, but since the girl is very clumsy, she ended up burning the forehead of the girl, which the more girl actually expected from her. the more mature girl actually love that clumsiness of the other girl, that she ended up not wanting to girl to change and be like that for the rest of her life. TIA
