On a typical, quiet afternoon, Izuku Midoriya, also known as Deku, and Katsuki Bakugo were lounging around in their dorm. They had finished their usual intense training at U.A. High School and had some free time on their hands.

As they rested, Bakugo randomly brought up a word that left Deku perplexed - Gacha Heat. He had overheard some junior students talking about it the previous day.

"Hey, Deku. Do you know what 'Gacha Heat' is?" Bakugo asked, glancing at his friend. Deku blinked, clearly puzzled. "Gacha Heat? No, I've never heard of it. Should I have?"

Bakugo shrugged. "I've heard some kids talking about it. Said it's on YouTube or something."

Curiosity piqued, Deku took out his phone. "Well, we have some time. Let's check it out," he suggested. Bakugo gave a noncommittal grunt in agreement.

Soon, they had pulled up a Gacha Heat video on YouTube. As the video played on, both their expressions began to change drastically.

Deku's expression was clearly showing shock and discomfort, while Bakugo seemed equally taken aback, his usual scowl darkening.

As the video ended, there was a moment of silence before Bakugo finally said, "So, that's Gacha Heat, huh? I'm seriously regretting asking about it now."

Deku nodded slowly, staring blankly at his phone screen. The video had been weird and made him feel uncomfortable. "Yeah... I really don't know what to say, Kacchan."

Bakugo scowled. "I don't get it. Why are these kids fascinated by this stuff?"

Deku was silent for a moment. "I don't know, Kacchan. Maybe it's just...a phase, or something? I mean, we all have different interests right?"

Bakugo grunted. "I guess. But this...this is just plain weird. And kind of inappropriate too, if you ask me."

Feeling uncomfortable, Deku decided it was best to change the subject. "Well, let's forget about it for now, Kacchan. We should probably focus on our upcoming exams."

Bakugo nodded, already seeming to forget about the Gacha Heat topic. "Right, we have an exam to ace. Let's get back to work, Deku."

Despite changing the topic, the Gacha Heat video left a lasting impression on both of them. It was a new insight into a part of youth culture that they found bizarre and uncomfortable.

It also sparked an important conversation between them about the impact of digital culture on kids. Both Deku and Bakugo realized the power and influence of the internet.

Deku felt like this experience had taught him something new about his generation. "The internet really has changed everything, hasn't it, Kacchan?"

Bakugo grumbled in agreement. "Yeah. Makes you think about what we put out there, doesn't it?"

And so, they left the conversation about Gacha Heat behind, but not without learning something valuable about their generation's interaction with the digital world.

Even though the whole experience was uncomfortable, it helped them understand the complexities of the digital world a bit better - how it can shape perceptions, tastes, and even morals.

In the end, they both agreed to not dwell on it any longer. After all, their main focus was on becoming better heroes, not pondering over YouTube trends.

As they carried on with their studies, the afternoon slowly eased into evening. The memory of Gacha Heat gradually faded into the background.

Yet, this short detour into digital culture served as a reminder for both of them. It was a strange and sometimes uncomfortable world out there on the internet, one they had to adapt to and learn to navigate.

The incident made them more aware of their influence as potential heroes and the responsibilities that came with it. They realized the importance of creating a better, safer space for everyone online.

So, even though the encounter with Gacha Heat on YouTube was unsettling, it had also been a learning experience for both Deku and Bakugo.
