Otonari Complex Vol. 3 by Saku Nonomura

After her childhood friend Makoto's sudden confession, Akira tries to face his feelings seriously, but she keeps getting self-conscious and going around in circles about it. She knows she can't go on acting this way, but Makoto keeps smiling at her with the face of a man she doesn't recognise. It all comes to a head when the pair finally agree to a date!
