@Modern boy YOU must be the illiterate since there's no "harem" tag here. Context clues? Are you so far from the real world to the point that you think that if more than the girl mc in a manga is attracted to the same guy then it automatically becomes a harem? Oh man
@just an ordinary bi*** but the problem is that, apart from the girl mc, not only 1 but 2 girls are in love with him and another 2 girls are interested in him and now this girl will probably be interested in him too. So in total there are now 6 girls in the story. So it's definitely a harem.
@just an ordinary bi*** One of the girl is Minami, she's always flirting/teasing the mc and she once told Asahi if she wanted to get the mc she would win. The other girl is Haruno, who is interested in him because she wants to know why her friends are in love with him. These 2 girls are not in love with him yet, but both of them are interested in him in some way.
@Ikot Minami (Asahi’s best friend) isn’t interested yet in the Mc. So far, she is a wingwoman for Asahi.
The mutual friend of Toma and Mona (Hinami?) isn’t interested in the Mc, she just roots for her two friends. Based on how she reacted when she met the Mc, she isn’t yet interested
and until the next chapter, we have no idea what role this new girl is going to play
