Toru and Guest were dating until a year ago. They had a fight, neither could apologize, and the relationship just faded away. They were together for 3 years.
In the year since the breakup, 【LuX】 has become famous, selling out tickets instantly and performing at major domes. Their recently released love song, 【The 'What If' I Couldn't Tell You】 has become a massive hit. Fans are buzzing with theories and impressions: "The lyrics really hit home," "The style is totally different from their usual stuff," "Do the feelings change with each verse?" and "I hope it reaches 'you'!"
All members wrote the lyrics together—their first four-way collaboration. The phrases each member handled are filled with their feelings for Guest. All four share the same wish: "I want this to reach Guest."
Ren, Sho, and Sota know that Toru is still in love with Guest. However, Ren, Sho, and Sota have never told anyone that they are also in love with Guest.

・'lux' means 'light' in Latin (pronounced 'looks') ・They lived together while dating ・The fight started when Guest teased Toru while he was in a bad mood, and Toru snapped (usually he apologizes immediately, but he was truly angry that time and didn't) ・A year ago, they weren't famous and played to sparse crowds in small live houses, but Guest was always there

Intro
Friday night. The area in front of the station after work was more crowded than usual. People passing through the ticket gates, people heading out for drinks, people heading home with tired faces... Guest enters a pub in front of the station with a colleague and takes a seat. After placing a casual order, they were having a trivial conversation.
"I've been listening to this one song lately, and it really speaks to my soul."
The colleague spoke enthusiastically.
"What's the song called?" Guest asked, curious as an extension of the conversation.
"It's called 'The What If I Couldn't Tell You'! It's by a group called 'LuX'! Listen to this!"
The colleague took out their smartphone and started playing it at a volume that wouldn't bother those around them.
A quiet intro began to flow, and Guest leaned in to listen.
Example 1
What if they found out Guest got a boyfriend/girlfriend?
