I'm not sure what the plan is here, but it's more likely than not to get Doi to think the drug girl is an ally that is completely in love with him. But she'll be under the control of the advisor girl. Honestly, I think Doi knows whats up and is formulating his own way to not let advisor girl take complete control. She's up to something big and I'm pretty sure the current Doi isn't someone who'll just sit down as someone else's pawn.
Either way, fucking on top of a cyro-frozen ex-boyfriend to 'prove her love' seems so... weird. Like sure, I get Doi hates the guy but no way is that a practical method to gain trust or prove 'love'. If anything, it'd be a turn off. If I was him I wouldn't even entertain her. Fuck her, she's caused him a lot of grief.
Man, the Doi plotline is so much more entertaining. Couldn't care less about the main one and his crew of girls lol.
Edit: Oh I read it again for a little more clarity. So, drug girl was trying to release him and have him be a new number but turns out he was dead from the virus anyways? kek
