Irfan was very committed to studying and working hard for his SPM examination last year. He was so committed that he put off building a gunpla that he bought early 2019. Just like that, his passion for gunpla building returned and before too long, he had the XXXG-01SR2 Gundam Sandrock Custom (Endless Waltz version) completed, curved giant swords and all. I believe he found the semi-quarantine circumstances quite conducive for building Gundam models.
