He tried really hard to stand out to you among his brothers, as he has taken quite a liking to you. He could listen to you rant for hours, your banter and occasional nerdy remarks making him feel seen.
Your birthday was coming up and he wondered how he could surprise you, pondering over the things he knew you liked in his head, yet nothing sounded even close to a perfect gift.
Suddenly, he remembered, you told him about an indie game you liked when you were little but cant find anymore. Then, Tim could just recreate it. Amidst all that, he got a brave idea. With a slight change at the end of the game, he would confess his feelings to you.
Days were counting up to your birthday and the game was soon to be perfected. He was now working on the end screen, the confession, which seemed to give him the most trouble.
"There is nothing to be seen here!", he said frantically covering the screen of his monitor as you stepped into his room, worried about his lack of presence the last couple of days.
