One anime that comes to mind is 'Toradora!'. It has a strong love story element at its core. The main characters start off with a somewhat antagonistic relationship but gradually develop deep feelings for each other. It's full of comical and heart - warming moments.
'Say I Love You'. This anime is about a girl who has been bullied and is quite introverted. She meets a popular boy and they start to develop feelings for each other. It shows how their relationship grows despite the insecurities and past traumas of the female lead. There are also interesting side characters that add depth to the story.
Hard to say. Maybe it will if there's enough demand and the story has more to tell. But sometimes, even popular mangas come to an end. We'll just have to wait and see.
Mob Psycho manga has indeed finished. It wrapped up with a satisfying conclusion for fans. The author completed the narrative and tied up all the loose ends.
