As he's my bestie and he admitted that he's the one who tagged my tagboard using 'passerby' and 'kkv' and I knew it all along, though he denied and denied but at last he admitted, so I guessed everything's solved.
Though I still doubt things. May he change and history'll not repeat again and again. (:
Still abit reluctant to forgive, but he said he'll prove to me/us he'll change.
Keep your words bestie!
