She does have a rather peculiar way of approaching her love interest. Too bad the dude hasn't got even the slightest clue about her interest in him.
I mean that would obviously be the last of his worries 🥲
She happened to safe his life, then just barged into his home and decided to live there and constantly messes with him, that mixed with the gyaru image, would obviously make him think exactly what her friend said 😶
I mean.. the beginning of the manga feels rather forced anyway 😮💨 The whole car scene was really just the authors justification to have her barge into his house
