Tomo-chan wa Onnanoko! EP9 - The Angel's True Face

A flashback reveals the moment Kosuke first met and became enamored with Carol. In the present, Kosuke enrolls into Goro's dojo, becoming overwhelmed. When asked by Tomo why did he enter, he reveals he wants to become stronger for Carol's sake. The next day, Carol mistakenly believes Kosuke is attracted to Tomo, so she goes into Junichiro's house to make him jealous. This does work, so Kosuke finally reveals his love for Carol to Misuzu, explaining he has been unable to tell her due to having never seen her vulnerable. To help him, Misuzu makes some painful comments regarding Kosuke's interest for her to Carol, making her flee the school, crying. Misuzu realizes her mistake, and sends Kosuke to her home. There, he tells Carol about Misuzu's lie, and finally confesses his love. Delighted, she accepts Kosuke's confession, and her mother trusts Carol to him after he promises she will not change the way she is for being in love, as she now has friends around her. The next day, Carol gets back at Misuzu by scaring her.
