I don't think robots can have emotions like love for manga. They don't have feelings or preferences like we do.
It depends on the specific manga. Some creators might incorporate the idea of robots having emotions like love to add depth to the story, while others may not. It all comes down to the author's imagination and the theme they want to convey.
Todoroki's love interest in the manga is kind of up in the air. The story doesn't really zero in on that aspect. It's all about his hero journey and growth for now.
It's not clearly defined in the manga. There are multiple characters who could potentially be seen as having some sort of connection with Ayanokoji, but no definite love interest.
In the Gunnm manga, Hugo is one of Alita's love interests.
There's a manga called 'Heartless Love' where the main character plans revenge on the love interest after being hurt emotionally and betrayed in a major way. The revenge plot adds a lot of drama and tension to the story.
You might want to check out 'ZZZ' manga. The fat love interest in it is depicted with depth and complexity, making the romance storyline all the more compelling.
You might want to check out 'Love Tyrant'. It has a unique take on the yandere love interest concept. The plot is full of surprises and the characters have depth.
I'd recommend 'Romantic Encounters'. In this manga, a milf plays a significant role as a love interest and the plot develops around their relationship in a captivating way. There are some unexpected twists and turns that keep you engaged.
A manga male love interest often has good looks, a charming personality, and is protective of the female lead.
Typically, the love interest in shoujo manga is depicted as being confident, maybe a bit aloof at first but warms up later. They usually have some sort of special talent or quality that attracts the heroine.
