Gaming rivalry is the second chapter of Bittersweet Candy Bowl. The chapter establishes the status of Mike and Lucy's relationship and the origins of Lucy's pink bow tie. This chapter marks the first chapter drawn in the original art style in Volume One.
The chapter begins with both Mike and Lucy at Mike's house playing competitively against each other in an arcade fighting game. The game ends when Lucy, finding herself in a corner, uses a move which gives her an advantage over Mike, killing his character despite having full health. Mike protests calling the move a cheat while Lucy calls him a sore loser, and they begin fighting over the validity of the move; Lucy arguing it's allowable since it's in the game, but Mike is persistent it's a cheat move and shouldn't be used because it's banned at tournaments.
Their argument is overheard by Yashy and Blur playing cards together nearby, and see this as another instance of romantic-infighting between the two. Yashy gets involved and tells them to make out somewhere else, additionally telling her mother (Lucy) it was only a game, with Lucy telling her she should say that to Mike, as he comments Lucy is so defensive it's like he's arguing with a thickheaded jock. Blur interjects suggesting they just have sex already, and is immediately kicked into the ceiling by Mike.
Yashy comments that Mike has a point about how boyish Lucy acts through her competitiveness, to which Lucy finds irrelevant. Mike support's Yashy's observation as he agrees to his lost, but points out Lucy is so arrogant she can't come to admit herself the move was unfair. Lucy ends up childishly pushing Mike as they continue fighting about the move. She asks if the real reason he's sore about losing is because he was beaten by a girl, to which Mike finds as a revelation stating he could never could have known she was a girl. Getting tired of their gender being made fun of, Lucy promptly knocks out Mike.
Yashy tells Lucy she shouldn't be worried that people find her masculine, mentioning why else would she continue to wear her pink bow - a present from her mother when Lucy began kindergarten in the first place. This is shown through two flashbacks, the first being a two year old Lucy playing with a toy car. Lucy's mother appears and hands Lucy a Barbie doll to see if Lucy would prefer playing with that toy instead. Rather than take to the new toy, Lucy instead plays with both toys by having the toy car run over the barbie doll.
The second flashback moves forward two years to a four year old Lucy being taken to Kindergarten. Lucy is immediately uninterested in playing with the other girls. Before leaving, her mother tells Lucy she has a present and wraps a pink Bow around her neck, telling her daughter she will always be her little girl despite her boyish quirks.
Mike recovers in the present time and makes fun of Lucy stating that even her own mother thought she was a boy. Lucy goes to punch him again but Mike dodges it, asking why she still wears it, prompting Yashy to cheekily state it's for reassurance she is biologically female. Lucy responds kicking her into the ceiling next to Blur.
Mike tells her not to be upset, stating he was only joking around, but still sour about the unfair move in the game. Lucy challenges Mike to the video game again, this time telling him he could use it as much as he wanted. Mike does so, beating her fifteen times in a row. Revealing he had secretly mastered the move himself as his sister also abused it when she played with him, progressively getting better at inputting the move as the game effectively became a process of who could pull off the move faster than the other. Lucy finds this advantage unfair to the thrill of Mike, and smugly turns the table on Lucy. Mike makes fun of her for looking cute when she's angry, as Lucy gets the idea to use it to her advantage and starts using a feminine charm against him. It works, catching him off-guard at the sudden change, all before backfiring as she hugs him into her chest, Mike reciprocating how soft it is before being thrown off. Mike recovers asking if she wants to play something else, to which Lucy agrees to.
With Lucy and Mike fighting soon after again, Yashy goes to end the tension by telling Blur she is taking her mother home. She playfully mounts Lucy like a horse telling a blushing Mike they have overstayed their welcome. When she tells her mother to 'giddy-up' she is instead kicked through the roof by Lucy. Lucy remarks how odd that was before asking Mike if there was another game they could play. Mike make a freudian-slip from the earlier stunt while mentioning another game, accidentally saying 'Sonic ride you' instead. He catches himself too late as Lucy looks back disgusted, ending the chapter.
