Two days ago, the unexpected happened to Ah Boys To Men star Noah Yap.
His enlistment letter, which he thought would come only later this year, arrived in his letter box.
The local actor has to enlist in the army on May 14.
After recovering from the shock, he decided that he would make the most of his remaining three weeks of "freedom" - which ironically happens to be immersing himself in his role as a recruit in the Ah Boys To Men: The Musical.
It is on at the Resorts World Theatre in Resorts World Sentosa till May 4.
Among the cast, which includes Wang Weiliang, 27, Tosh Zhang, 24, Maxi Lim, 27 and Benjamin Kheng, 23, Yap is the only one who has not served national service.
He was previously studying at the Nanyang Academy Of Fine Arts.
The 21-year-old told The New Paper: "I'm going to keep a low profile by shutting up. I will do as I'm told. In real life, I'm very obedient.
"I don't want to give my army mates the impression that I'm making a fuss about anything," he said. Yap said he wants to "experience the army just like everyone else".
When asked if he would oblige army mates who are fans, he said he does not consider himself famous.
"It's nice to receive all this support. If someone wants an autograph for his relative or something, I'll sign it, but I think after that, it would be quite awkward between us," he said.
Yap has already been the victim of a prank, thanks to his cheeky fellow cast members.
On Tuesday night, he took his enlistment letter to the show and showed it to them during rehearsals.
Before he went on stage, Yap realised that his letter had gone missing.
In a scene during the musical, the boys receive their enlistment letters.
The other boys had stolen Yap's enlistment letter and swopped the prop letter with the real deal.
For Yap, he had to hide his shock so the show could go on.
He said: "First thing I thought was, 'What the hell! Must be Ben or Tosh'. All of them were laughing backstage during my scene."
Yap said he is not like IP Man, his character in the movie and musical. IP Man is sensitive, cries easily and is all nerves when his head gets shaved.
Yap, in contrast, hopes to take every challenge in his stride, including his impending enlistment.
The lanky 1.71m-tall YouTube personality is secretive about his weight though he was open about wanting to join the SAF Music and Drama Company.
He said: "I'm not worried because filming the two Ah Boys movies and doing this musical has prepared me for NS. So the mystery (of NS) has been eliminated in a sense.
"My only goal is that I would love to become very buff. It's a new phase in life and I'm just going to be myself," he added.
