His friends would probably take care of him. Midoriya would be very eager to help, using his kind-hearted nature. He would make sure Todoroki is fed and comfortable.
One idea could be that all his friends at UA plan a surprise birthday party for him. They decorate the common room with his favorite colors, blue and red. Another plot could be Todoroki spending his birthday with his family, trying to reconcile with his father on this special day. Maybe he receives a heartfelt gift from his mother that has a deep emotional significance.
Todoroki's character development in time travel fanfictions can be quite profound. He may start as a somewhat aloof character, but through time travel, he begins to understand the importance of relationships more deeply. When he travels back and witnesses the relationships he could have had or lost, it makes him cherish the ones he has in his original timeline. His view of heroism also evolves. He realizes that being a hero isn't just about using his powers but also about making the right choices at the right time, which is especially highlighted when he has to make decisions that could change entire timelines.
Crying could be described according to different situations and characters. There were a few possible ways to describe it:
1. Crying sadly: The eyes are red and swollen, and the tears are constantly flowing. The lips are slightly opened, as if they are silently pouring out the pain in their hearts.
2. Crying in despair: Tears poured out like a waterfall. His eyes were hazy and he looked depressed as if he had lost all his strength.
3. Crying angrily: The eyes are red and swollen, and the tears are like boiling flames. The expression on the face also becomes angry and resentful.
4. Crying in surprise: Tears instantly gushed out of her eyes as if expressing her inner ecstasy and gratitude.
5. Crying in fear: Tears flow from the eyes. The trembling body and helpless heart make people feel fear and uneasiness in their hearts.
Different crying forms could show the character's inner emotions and personality characteristics, and at the same time, it could allow the reader to better understand the character's psychological state.
In the fanfiction, their relationship could start with a bit of competition. Both are ambitious to be heroes. However, they soon realize that they can achieve more by working together. As kids, they might compete in small challenges like who can run faster or jump higher using their quirks (or in Izuku's case, his physical training). This healthy competition could fuel their growth and transform into a deep - rooted friendship that withstands all the difficulties they face later in their hero careers.
