Hello, i don't know if anyone already asked this. But please help me if you know. Thank you before.

So, this is a shoujo manga . If i'm not wrong there was a scene where female main character bought some supplies for her "brother" but unfortunately she met a boy who mistaken her and said she must be stalk him after saw a boxer she bought. (I believe she was in love with him and even confessed to him, but idk, i really want to bang my head because of this hazy memory).

Please help me and thank you.
