A New Start for Saitama

This is my very first time making a fanfiction so I'm looking for constructive criticism and or advice the characters will be ooc as this is my first time

Well I guess I have to do a disclaimer cause I always see it I don't own One Punch Man or else tatsumaki would love Saitama?

Saitama had just woken up awhile ago and doing so he started his morning routine so he watered his cactus and was thinking what he should do for breakfast when his thoughts were interrupted by a certain cyborg. "Sensei what would you want for breakfast I have multiple dishes downloaded on my database that I could serve and make ?" Said the cyborg to Saitama as he started thinking 'Huh who was he and what was he doing in his apartment.' "Ah what are you doing and who are you" Saitama asked the cyborg "Do you not remember me master I asked if I could be your disciple yesterday after you took down that humanoid mosquito.."said the cyborg as his voice faded into the distance while he started thinking 'Wait he isn't making this up is he crap I completely forgot' he cringed internally whatever can't be that bad. What he didn't know was that his life would become different after that day.

Soon after that mess with the cyborg and after i finished this exam so i could become a real superhero 'even though i had done way more then the organization knows' i met a girl with green hair who could move things with her mind she called it ESP and he didn't know what it was about her but something he felt that I hadn't been there for years he thought lost Emotion!? But he hadn't felt anything like that in a long time.

:Time skip after his fight with boros:

"Hey I'm finally out" he said after his fight with Boros "HEY baldy what we're you doing in there?" said Tatsumaki in an angry and worried tone. "I beat there boss what else would I be doing" he said to her in a confused tone. Tatsumaki started to talking really fast saying "What how could you take him out and plus that ship must've been loaded with monster how could you even do that all by yourself much less come out unscathed" She said worried almost tearing up which surprised him as she was always very serious and would always be angry with him for some reason or another. But as he looked up he saw her face she looked so...cute while she was almost crying. "Hey stop crying little kid I'm right here safe and sound" He said in a sarcastic tone to the now angry esper knowing knowing his comment would snap her out of situations thoughts. She started yelling "Well it's not my fault I was worried about you as soon as your robot said you were going in their on your own well know that I know your okay your deserve to suffer as I will tell you your punishment.." 'Punishment what did I do' he thought "... You must take me out for dinner" She stuttered the last part as she was blushing a wonderful shade of pink. When he saw her he thought she was so cute but then he snapped out of it as he said "So you want to go out on a date?" Her face turned into the color of a ripe tomato as she blushed "Nnno it's not like that its just for making me worried and wasting my time thinking about you." I got nothin else to do so why not and getting to go out with her was a treat as he liked her very much "Sure when do you want go out?" He asked the esper to which she responded "tomorrow at 6pm pick me up at my place and don't bring your robot boyfriend" She said in a demanding tone not asking him while giving him her address "yeah it works oh and I don't like guys" whe he said he thought about her not knowing why. As he walked away knowing what would happen "well see you tomorrow tats" calling over Geno's as he was leaving. "I told you to stop calling me that stupid baldy hmph" as she puffed her cheeks out while blushing but she took her leave knowing she would have to get ready for tomorrow as she needed to look good for him tomorrow and it would be another day.
