π Subscriber Request Alert! A few subscribers have been asking me to break down that viral π “Weak Hero Class Change” video where the actors switch roles and perform each other’s iconic lines.
So here we are! Today I’m giving you the full breakdown of what’s actually happening when Park Ji-hoon tries to channel Baku’s energy, why everyone was laughing, and the brilliant character contrasts this role-switching exercise reveals.
Video Concept Overview
This is a special promotional video where the Weak Hero Class 2 actors switch roles and perform each other’s iconic lines. The format has each actor first deliver their own character’s signature dialogue, then attempt to mimic another character’s memorable lines.

Actor-by-Actor Role Switch Analysis
1. Yoo Soo-bin (Choi Hyo-man) β Acting as Na Baek-jin
- Own Character Line: “No, I have something to repay. Hey Si-eun, should I fucking gather the kids right now? Huh?”
- Imitating Baek-jin: “You said you’d do everything I want, right? If you do that, I’ll also do what you want”
Contrast: Complete shift from Hyo-man’s direct, aggressive tone to Baek-jin’s calculated, conditional negotiation style
2. Bae Na-ra (Na Baek-jin) β Acting as Go-tak
- Own Character Line: “I told you to separate the variables first, right? But there’s a better way. If you eliminate the variables, it’s much faster”
- Imitating Go-tak: “Hey, you fucking idiot! You bastard who scored 99 on an IQ test, what’s in your damn head?”
Contrast: Dramatic change from Baek-jin’s cold, logical speech to Go-tak’s passionate, direct action
3. Lee Min-jae (Go-tak) β Acting as Seo Jun-tae
- Own Character Line: “Hey, you fucking idiot! You bastard who scored 99 on an IQ test, what’s in your damn head?”
- Imitating Jun-tae: “I don’t think it’s because of you. I wanted to tell you it’s not your fault”
Contrast: Dramatic shift from Go-tak’s explosive, aggressive action to Jun-tae’s gentle, comforting reassurance
4. Choi Min-young (Seo Jun-tae) β Acting as Yeon Si-eun
- Own Character Line: “I don’t think it’s because of you. I wanted to tell you it’s not your fault”
- Imitating Si-eun: “Jun-tae, I’m just more comfortable alone”
Contrast: Shift from Jun-tae’s warm, comforting tone to Si-eun’s cold, distancing manner

“Jun-tae, I’m just more comfortable alone…”
5. Park Ji-hoon (Yeon Si-eun) β Acting as Baku
- Own Character Line: “Su-ho, sorry I’m late… The things you taught me about how it’s good to have friends, how it’s good to smile… I want to try doing those things for the kids too”
- Imitating Baku: “I figured it out clearly this time – you and I fucking don’t match”
Contrast: Complete opposition from Si-eun’s emotional, sincere confession to Baku’s direct, rough declaration
6. Ryeoun (Baku) β Acting as Geum Seong-je
- Own Character Line: “I figured it out clearly this time – you and I fucking don’t match”
- Imitating Seong-je: “Anyway, these Eunjang bastards are so fucking entertaining. Okay, romantic approved”
Contrast: Change from Baku’s serious, firm tone to Seong-je’s relaxed, playful manner
7. Lee Jun-young (Geum Seong-je) β Acting as Choi Hyo-man
- Own Character Line: “But this bastard won’t blink his eyes”
- Imitating Hyo-man: “Seong-je, I’m Hyo-man. I’ll definitely bring 100 by next week. I don’t usually make mistakes like this, you know I’m loyal, right?”
Contrast: Shift from Seong-je’s cynical, observational tone to Hyo-man’s desperate, loyal pleading
Why Did the Actors Laugh?
Park Ji-hoon’s Shy Laughter
Park Ji-hoon laughed when delivering Baku’s line “fucking don’t match” because his usually gentle image made it awkward to use rough language. Especially saying the strong curse word “μ‘΄λ” (fucking) made him naturally shy and embarrassed.
