Please help me find a manga

I'm looking for a manga whose characters are high school students. The main characters are probably childhood friends. A girl appears between them and she is in love with a tall boy, and the short one helps her confess her feelings, then he feels something for her and they start dating. It seems to be a male-female romance, but later it turns out that the tall boy is in love with the short one and we have some drama in the group of friends because of it. Please help me find this manga because I wanted to read it again but I can't remember the title.
