If your boyfriend hasn't opened Claude Code / Codex these past two days, isn't spouting about the "supercycle of semiconductors," DRAM, NAND, HBM, PCB are always out of stock, isn't suddenly researching Korea's national fortune, such as SK Hynix being an AI shovel stock, Samsung being the world's top profit maker next year, Doosan Energy being Korea's version of GEV, and not feeling emotional late at night about this being the national destiny or East Asian manufacturing revival.

It shows he has no investment or financial management concepts, can't understand industry trends, and has missed the beta of the era.
But it also indicates he won't be tempted by bubbles, has no FOMO, won't go all-in at the top, and won't call being trapped a long-term strategy.
Such a man is emotionally stable, and his account is stable as well.
He can be considered for marriage.
